can malfunction or become hazardous in the hands of an inexperienced and/or untrained user. Therefore, read this manual
and related equipment manuals thoroughly before operating your HydraCutter to provide maximum safety for all operating
personnel, and to get the maximum benefit from your equipment.
1.2 SAFETY DEFINITIONS
A safety message alerts you to potential hazards which could injure you or others or cause property damage. The safety
messages or signal words for product safety signs are DANGER, WARNING, and CAUTION. Each safety message is
preceded by a safety alert symbol and is defined as follows:
DANGER: Indicates an imminently hazardous situation which, if not avoided, will cause death or serious injury. This
safety message is limited to the most extreme situations.
WARNING: Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
CAUTION: Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. It
may also be used to alert against unsafe practices that may result in property-damage-only accidents.
1.3 POWER SOURCE AND HYDRACUTTER SAFETY LABELS
These labels warn you of potential hazards that could cause injury. Read them carefully. If a label comes off or becomes
illegible, contact Reimann & Georger Corporation for a replacement.
1.4 MINIHYDRACUTTER SAFETY RULES
1.

OPERATION
3.1 CHAIN SELECTION
Correct chain type selection is critical in maximizing chain life and cutting performance. Refer to the table below as a
guide in the chain selection. However, no direct rule determines which chain type is optimum because many material
factors also influence selection. Refer to Chapter 6 for more information on factors affecting chain life.
Model
SL25
(50 or 55
segments)
Description
For cutting hard/very hard aggregate concrete (flint, chert, granite, etc.) with heavy steel reinforcing.
Heavy steel reinforcing is defined as 5/8” [16 mm] or larger rebar—1/2 closer than 4” o.c. (“on
center”). The SL25 has a higher diamond concentration than the SL45 with a softer matrix.
It is not advisable to use this chain on soft or medium aggregate concrete, masonry brick, concrete
block, or under highly abrasive conditions.
SL25
(50 or 55
segments)
For cutting medium soft/medium hard aggregate concrete (granite, quartz, river rock, etc.) with
moderate steel reinforcing. Moderate steel reinforcing is defined as (1/2” [13 mm] or smaller rebar) 1/2 farther than 4” o.c.
It is not advisable to use this chain on heavy steel reinforcing (5/8” [16 mm] diameter & larger), soft
or very hard aggregate concrete, masonry brick, or concrete block.
SL45
(50 or 55
segments)
For cutting soft/medium soft aggregate such as abrasive and “green” concrete, concrete block,
masonry brick or under highly abrasive conditions
Do NOT use this chain on any type of steel reinforcing, or medium or very hard aggregate concrete.
3.2 BEFORE OPERATING THE HYDRACUTTER
The following systems must be checked before you can use the HydraCutter safely. Running the HydraCutter with an
undetected defect in any of these systems will quickly cause equipment damage.
1.
Hydraulic system
2.
Water supply and distribution
3.
Chain and bar
3.2.1 CHECKING THE SYSTEM HYDRAULICS
1.
Read and fully understand the operating manual for the hydraulic power source being used.
2.
Always check the hydraulic power supply flow and pressure output. Never exceed the maximum hydraulic flow rate
of 8 gpm (30 lpm) and maximum pressure of 2500 psi (172 bar). Overspeeding the chain causes increased chain
wear, leading to loss of strength and possible chain breakage.
3.
If the oil flow from the hydraulic power supply cannot be adjusted below the maximum flow rate, a flow divider must
be installed. This will ensure the HydraCutter receives the correct flow and excess oil is returned to the tank.
4.
To protect the HydraCutter from excessive pressure, the pressure relief valve of the hydraulic power source must be
set at 2300 psi (158 bar). If this is not possible, a separate pressure relief valve set at 2500 psi (172 bar) must be
installed in the system. If in doubt, contact your dealer.
5.
The hydraulic power source must be fitted with a 10-25 micron oil filter.
6.
Before making any hydraulic connections, inspect all hoses for leaks and risks of rupture as follows:
5
a.
Inspect each hose for breaks, cracks, worn spots, bulges, chemical attack, kinks or any other damage. Never try
to stop any detected leak with any body parts. Do not put your face close to suspected leaks. Hold a piece of
cardboard close to suspected leaks and then inspect the cardboard for signs of hydraulic oil.
b.
Replace a damaged hose immediately. Never repair the hose.
WARNING:
LIQUID UNDER HIGH PRESSURE CAN PIERCE THE SKIN, CAUSING DEATH OR SERIOUS
INJURY. IN CASE OF INJURY, GET IMMEDIATE MEDICAL ATTENTION.
The HydraCutter uses flush-face quick-release couplings that are durable and easy to clean. Wipe the mating surfaces of
the couplings with clean rag prior to making connection. They are always fitted such that the male part gives oil and the
female part receives oil.
WARNING:
ENSURE HYDRAULIC HOSES ARE PROPERLY CONNECTED AND IN GOOD CONDITION.
3.2.2
Checking Water Supply
1.
The water supply must be connected and tested before operating the HydraCutter. Check for proper water distribution
by triggering the HydraCutter with the hydraulic power supply off and the chain not yet installed. You should see
water coming out the three water ports each on the top and bottom of the bar and around the nose sprocket. If not, use
a #10 wire to clean the water ports, keeping in mind that the water ports are tilted forward at 30 degrees.
2.
The water pressure at the HydraCutter must be between 50–160 psi (3–9.6 bar) with a flow rate of 2.5 gpm (9 lpm).
For best performance, use an RGC in-line water pump. Permanent chain, bar, and drive and nose sprocket
damage will occur if the HydraCutter is run without water, or with a water volume or pressure that is too low.
This damage can include excessive chain stretching, excessive drive and nose sprocket wear, and shorter chain
life. The recommended water pressure for most applications is between 80–100 psi.
3.2.3
Checking Chain and Bar
1.
The bottom rail wears at a much faster rate than the top rail because of the downward motion during cutting. It is
recommended that the bar be turned over on a regular basis to ensure even wear.
2.
Inspect the chain for cracks, missing segments or bumpers, or signs of overheating (discoloration) or other damage
before mounting and before each use.
3.
Inspect the chain chassis for wear. Wearing of the chain chassis is typically referred to as “chain stretch.” If the bar
adjustment screw cannot be tightened sufficiently to prevent the drive tangs from coming completely out of the
groove, the chain chassis is considered to be excessively stretched. Discard the chain.
4.
Inspect the cutting segment for wear. The segment is considered worn out when the segment height is worn to about
1/16”, or when the segment and chain chassis are the same width.
6
Figure 3-1.
Proper Chain Mounting
5.
The chain MUST be installed with the bumper link leading the diamond segment. See Figure 3-1. Backward
(reverse) chain installation can cause excessive vibration, rough cutting, reduced chain life, and chain
breakage.
6.
Check for proper chain tension as described in Chapter 4.
7.
Check that the chain guard is in the mounting grooves and that the socket head screw is tight.
8.
Always operate a new chain at the rated rpm for two minutes before cutting to verify proper chain mounting and
tension. The chain should be moving away from you (i.e., forward direction) at the top of the power bar. If it is not,
change the position of the forward/reverse lever on the power unit, if equipped, or reverse hydraulic connections at
power unit.
3.3 PLANNING THE CUT
1.
This HydraCutter is not insulated. Do not start cutting without first de-energizing electrical wiring imbedded in the
concrete and near the cutting site.
2.
When cutting a structural member such as a wall, ensure the cut will not weaken the structure such that it will cause a
failure.
3.
Plan the sequence of cuts to prevent the weight of the material being cut from pinching the bar and chain, causing it to
bind. Start with the base horizontal cut and proceed with the remaining cuts.
4.
The material being cut must be rigidly supported to prevent it from falling and causing personnel injury.
5.
The planned line of cut can be outlined with a permanent marker for a visual guide.
6.
For long vertical or horizontal cuts, the cutting line can be first scored with a groove using the nose of the bar. The
groove will help guide the bar for a straight cut.
3.4 BREAKING IN A NEW CHAIN
1.
Before using a new chain, the cutting segments must be dressed by cutting in an abrasive material such as cinder
blocks or bricks.
2.
Looking at the cutting segment closely, you should be able to see the diamond particles exposed, raised slightly higher
than the surrounding surface.
3.
Check the chain tension frequently during the first thirty minutes of operation of a new chain.
7
3.5 CUTTING PROCEDURE
WARNING:
THE CHAIN GUARD MUST BE IN PLACE BEFORE STARTUP AND DURING SAW
OPERATION. FAILURE TO DO THIS CAN CAUSE SERIOUS PERSONAL INJURY.
1.
Review all safety procedures in Chapter 1 of this manual and in the manual supplied with your hydraulic power unit.
2.
Grasp the auxiliary handle with your left hand. Use the appropriate part of the handle for making the first cut.
3.
Grasp the trigger with your right hand.
4.
Position the HydraCutter in the appropriate place to make the desired cut.
5.
Disengage the trigger lockout. Then depress (squeeze) the trigger to start the HydraCutter.
6.
When putting the chain into an existing cut, the cut must be the same width as the chain. Putting the chain into an
existing cut narrower than the chain will rapidly wear the side clearance of the chain and could cause chain breakage.
7.
When starting a cut, do not bang the chain into the cutting medium. Jarring impacts can decrease the life and
performance of the chain.
8.
Plan the cutting strategy before starting. Once the HydraCutter starts cutting, you cannot change direction of a cut
easily. Do not twist the bar in the cut.
9.
Do not apply excessive feed force. A constant chain speed is important for optimum cutting.
10. When plunge cutting, increase the opening of the cut by rocking the HydraCutter up and down. Aggressive plunge
forces may cause the HydraCutter to jam when exiting the cut. If the HydraCutter does become jammed in a plunge
cut, you can release the HydraCutter as described in Chapter 5.
11. The wall walker attachment, shown in Figure 3-2, can be used to provide mechanical advantage during horizontal and
vertical cuts. By inserting the wall walker into the HydraCutter kerf, a forward feed force is changed into a downward
feed force.
12. Check chain tension frequently during cutting.
3.6 SHUTTING DOWN AND STORING THE HYDRACUTTER
1.
Stop the HydraCutter by releasing the trigger lever.
2.
Stop the hydraulic power source following the procedure in the respective instruction manual.
3.
Clean the slurry off the HydraCutter with water before it dries.
4.
Shut off water supply.
5.
Disconnect the hydraulic hoses from the HydraCutter.
WARNING:
NEVER DISCONNECT ANY HYDRAULICALLY OPERATED PART OF THE SAW OR
REMOVE HYDRAULIC COMPONENTS, LINES, OR FITTINGS WHILE THE POWER
SOURCE IS RUNNING OR WHENEVER THE HYDRAULIC FLUID IS HOT.
Allow the water to drain out of the HydraCutter by pointing the nose down and triggering the valve on. If available, blow
the water out of the HydraCutter with compressed air. Spray entire HydraCutter with a light coating of oil to make
cleanup easier next time. Make sure the chain, bar, and bar nose sprocket have a coating of oil to prevent rusting.
8
6.
Secure the HydraCutter and hydraulic power source to prevent unauthorized use.
7.
Store the HydraCutter away from excessive heat or moisture. Store in a clean, dry area away from exposure to high
humidity, water, other liquids, or freezing temperatures. Avoid temperatures low enough to cause condensation on the
chain when moving it from storage to a higher temperature. Always handle and store chains carefully.
8.
Do not stack material on top of the HydraCutter that may cause the chain or bar to bend or deform.

INSPECTION AND MAINTENANCE
4.1 GENERAL MAINTENANCE RULES
Hydraulic fluid can become contaminated after extended periods of use which can cause restrictions in the system. Check to see
that the fluid is clean, and change at recommended intervals to extend MiniSaw’s life. Refer to the respective manual for
maintenance information on the hydraulic power source.
1.
Proper maintenance of the MiniSaw and related equipment requires timely adhering to all the guidelines given in this
chapter. Proper maintenance is required to maintain the system in good condition and free of defects.
2.
Review and follow all the safety rules given in Chapter 1 before attempting any maintenance.
3.
Only authorized personnel should be allowed in the maintenance area. Authorized personnel are the trained people as
defined below and their supervision.
4.
Repairs must be made only by trained personnel. A trained person is one who has read and thoroughly understands this
instruction manual and related equipment manuals and, through training and experience, has shown knowledge regarding the
safe operational procedures.
CAUTION:
BEFORE STARTING ANY MAINTENANCE, DISCONNECT SAW FROM HYDRAULIC POWER
SOURCE TO PREVENT ACCIDENTAL STARTUP.
WARNING:
DURING ANY MAINTENANCE OR REPAIR PROCEDURES, DO NOT ATTEMPT ANY
SAWING. THIS CAN CAUSE EQUIPMENT DAMAGE AND/OR PERSONAL INJURY.
4.2 BAR INSPECTION AND MAINTENANCE
1.
Before installing the bar, insure the bar is not bent or twisted.
2.
Ensure that the bar rails are dressed squarely as shown in Figure 4-1 with the wire edges removed. As the bar rails wear
down, sharp burrs are formed on the edge of the rails, which are typically referred to as wire edges. If ignored, wire edges
mushroom over and affect cutting performance.
3.
Ensure the nose sprocket rotates freely.
4.
Check the clearance between the nose of the bar side-plates and the chain chassis; when new, there is 1/32” clearance. The
nose sprocket must be replaced before the chain chassis begins to ride directly on the nose of the bar side-plates. Refer to
Figure 4-2.
5.
The bottom rail wears at a much faster rate than the top rail because of the downward motion during cutting. It is
recommended that the bar be turned over on a regular basis to ensure even wear.
6.
Check the bar rail wear. The bar is considered worn-out when any section of the chain groove bottom contacts the chain.
7.
Install the bar on the two mounting studs (28) and align the bar adjust pin (45) to the hole on the bar as shown in Figure 7-2.
Install the chain cover and install the two flanged hex nut. Use the 9/16” box wrench to securely fasten the flanged nuts
(#29).
8.
Check the water ports for proper water distribution by triggering the MiniSaw with the water connected and hydraulics
disconnected. Water should be coming out of the three water ports each on the top and bottom of the bar and around the
nose sprocket. If not, use a #10 wire to clean the water ports. Note that water ports are tilted forward at a 30° angle.
9.
Ensure water is completely drained out of the MiniSaw. If available, blow the water out with compressed air.
10
CAUTION:
NEVER RUN THE SAW WITH PLUGGED WATER PORTS. THIS CAN CAUSE
OVERHEATING AND RESULTING EQUIPMENT DAMAGE.
10. Ensure the bar and nose sprocket have a light coat of oil to prevent rusting.
Figure 4-1
Dressed Bar Rail
4.3 NOSE SPROCKET REPLACEMENT
The nose sprocket will wear more quickly than the bar rails under normal working conditions. When new, there is 1/32”
clearance between the nose of the bar side-plates and the chain chassis. The nose sprocket must be replaced before the chain
chassis begins to ride directly on the nose of the bar side-plates.
Figure 4-2
Nose Sprocket Clearance
1.
Using the chain breaker, punch out the six rivets and discard.
2.
Use a slotted screwdriver to carefully spread the bar side-plates apart. Be careful not to deform the bar side-plates by overbending them.
3.
Use a rag or paper towel to clean the nose sprocket area. Inspect the inner surfaces where the bearings ride. If a groove has
formed, it is not advisable to replace the nose sprocket. Replace the bar instead.
4.
With the side-plates spread apart the minimum space needed, install the new nose sprocket by sliding the assembly on the
insertion card into position. Align the six rivet holes. Insert the six rivets into the holes without breaking through the
insertion card and lightly hold them in place. Carefully remove the insertion card and screwdriver.
5.
Place the insertion card over the rivets. Holding the rivets in place with the insertion card, turn the bar over onto a flat steel
surface. Remove and discard insertion card. With the bar solidly supported on a flat steel surface, carefully peen the rivet
heads with the flat end of a hammer. Be very careful not to hit the bar body because it will pinch the nose sprocket. Rivet
11
heads must completely fill the countersinks in the bar body to hold the nose sprocket securely while still allowing the
sprocket to turn freely.
6.
File the rivet heads as close to the bar body as possible.
A. Trantorque® bushing
B. Drive sprocket
Figure 4-3
Sprocket Assembly
4.4 DRIVE SPROCKET INSPECTION AND INSTALLATION
Refer to Figure 4-3. The sprocket assembly consists of the Trantorque® bushing “A” and the drive sprocket “B.” Proceed as
follows:
1.
Check the wear marks on the driving face. Replace the drive sprocket before the wear marks are deeper than 1/32” as shown
in Figure 4-4. The outside diameter is also wearing surface. Do NOT turn around and continue using a worn drive sprocket.
A worn drive sprocket will increase wear on the chain chassis.
2.
Before installing the drive sprocket, carefully inspect the Trantorque® bushing for scoring on the inside diameter, dried
slurry or other debris on the threads and between the moving parts of the assembly. Do NOT lubricate the bushing.
3.
Slide Trantorque® onto shaft so that shaft extends completely through the bore.
4.
Slide the drive sprocket over the Trantorque® so that gold portion is within the bore approximately 1/16” past the edge. Be
sure the nut flats protrude so that a wrench can be used.
5.
Hand tighten the Trantorque® nut clockwise until snug. Looking from the top, the center of the drive sprocket must be
centered with the bar groove.
6.
Make any fine adjustments to the position of the drive sprocket. Holding the drive sprocket with the supplied drive sprocket
lock handle, tighten the nut of the unit with a torque wrench to 200 in.-lbs., 17 ft.-lbs., or 22.6 newton-meters. Do NOT use
a pipe wrench or pliers.

Sprocket Wear Measurement
4.5 CHAIN INSPECTION AND MAINTENANCE
Inspect the chain before mounting and before each use.
1.
Ensure there are no missing segments or bumpers. There must be either 50 or 76 segments.
2.
Ensure there are no signs of cracking, overheating, or other damage.
3.
Check the wear of the chain chassis, typically referred to as “chain stretch”, by tensioning the chain as described in Section
4.6. The chain chassis is considered worn out or excessively “stretched” if the chain cannot be tensioned sufficiently to
prevent the drive tangs from coming completely out of the groove. Discard the chain.
4.
Check the segment wear. The segment is considered worn-out when the height is worn down to about 1/16”, or when the
segment width is the same as the chain chassis.
After each use clean the slurry and debris off the chain; then apply a light coating of oil to prevent rusting.
A broken chain that is not worn-out can be repaired. There is a complete line of chain repair accessories available from RGC.
Separate instruction manuals are provided for the chain breaker and rivet spinner. Read these manuals before attempting these
repair procedures.
4.6 CHAIN INSTALLATION AND TENSIONING
Refer to the Figure 7-1, 7-2, & 7-3 assembly drawings in Chapter 7 throughout the following procedure.
WARNING:
FAILURE TO DISCONNECT THE POWER SUPPLY BEFORE STARTING CAN CAUSE
EQUIPMENT DAMAGE AND/OR PERSONAL INJURY.
1.
Ensure the hydraulic hoses to the MiniSaw are disconnected before starting.
2.
Loosen and remove the two flanged hex nuts (#29) and remove chain cover (#19). Next back out the bar adjustment screw
(#45) all the way by turning it counter-clockwise.
3.
Inspect the drive sprocket (#32) and the bar as described in sections 4.4 and 4.2 respectively.
4.
Install the chain by placing it around the drive sprocket making sure the bumpers lead the segments. Then, run the drive
tangs into the top groove of the bar and rotate it around the bar. Backward (reverse) chain installation can cause
excessive vibration, rough cutting, reduced chain life, and chain breakage. Make sure all drive link tangs are positioned
inside the groove of the bar.
13
5.
Install the chain cover (#19) and install the two flanged hex nuts (#29) but do not tighten at this time. Tighten the bar
adjustment screw (#45) clockwise until chain is snug to the bar but still able to rotate around the bar. Chain tension needs to
be readjusted before the drive tangs can come completely out of the groove.
CAUTION:
IF THE CHAIN IS TOO LOOSE DURING SAW OPERATION, THERE IS AN INCREASED
RISK OF CHAIN THROWING.
6.
Tighten the two flanged hex nuts (#29).
WARNING:
NEVER OPERATE THE SAW WITHOUT THE GUARD INSTALLED. DOING THIS CAN
CAUSE PERSONAL INJURY.

FACTORS AFFECTING CHAIN LIFE
Optimum performance from your chain saw will depend largely on selecting the proper chain for the application. If the cutting
medium is too soft for the chain rating used, you may get fast chain wear. If the cutting medium is too hard for the chain rating
used, you will get segment glazing and/or very poor cutting performance. This chapter is a guide in making the proper chain
selection.
6.1 HOW DIAMOND SEGMENTS WORK
Cutting concrete, stone, and other hard, brittle materials is a grinding or abrading action. Cutting segments are composed of
hard, abrasion resistant diamond particles distributed randomly in a metal matrix. The diamonds abrade or scratch out particles
of the hard substrates during the cutting operation. Even though diamond is the hardest substance known to man, it does wear out
or break down. New diamonds are exposed as the metal bond wears away. Abrasive particles will wear down a metal bond
faster than hard, brittle particles.
6.2 MATERIAL FACTORS AFFECTING CHAIN LIFE
There are several material factors that affect the performance and life of diamond segmented chain. Six major factors are
summarized as follows:
1.
Aggregate Hardness—There are many different types of rocks used as concrete aggregate. Some aggregates are very hard
like flint and some are very soft like limestone. A general rule is that the harder the aggregate, the softer the segment bond
that is needed. Another general rule is that the harder the aggregate, the slower the chain will cut. A common way of
measuring aggregate hardness is the Moh’s Scratch Test.

2.
Aggregate Size—As the rock size increases, cutting generally will be slower and the chain life will decrease. Common U.S.
aggregate sizes are sieved at 1-1/2”, 1”, 3/4”, and 3/8”.
3.
Size and Quantity of Reinforcing—Steel reinforcing critically affects diamond chain life. Quantifying the amount of
reinforcing can generally be divided into two levels:
18
Heavy
• 5/8” (16 mm) diameter or larger with any center distance
• 1/2” (13 mm) diameter or larger with less than 4” (100 mm) center distance
• Pre-stressed cable/wire
Light
• 1/2” (13 mm) diameter with greater than 4” (100 mm) center distance
• 3/8” (10 mm), 1/4” (6 mm) or smaller diameter with any center distance
• Wire mesh
Steel reinforcing creates large impact forces on both the diamonds and the chain chassis, reducing both the segment life and
chain life. Generally, as the ratio of steel in the concrete cross section increases, the performance and chain life are greatly
reduced. When steel is encountered while cutting, the feed force should be reduced.
4.
Sand Shape—Angular types of sand such as manufactured (crushed) and bank sand are more abrasive than rounded sand
such as river or wind-blown sand.
Angular sands decrease both the segment life and chain life. The diamond segment bond is abraded at a higher rate. Sharp,
fine sand increases the wear on the chain chassis, especially if the sand penetrates the rivet joints. Proper water flow rate is
critical in maximizing chain life in abrasive conditions. Generally, a harder segment bond is desired for abrasive conditions.
5.
Compressive Strength of Concrete—Strength of concrete is a combination of many factors and is usually measured in
pounds per square inch (psi). Even though the compressive strength does not indicate the aggregate hardness, there is a
relationship between the compressive strength and the hardness of the concrete. A general rule is that the higher the
compressive strength, the harder the concrete. Generally, higher strength concretes decrease expected chain life.

Green or Cured Concrete—A very important material factor is the cure time of the concrete. Green concrete is fresh poured,
typically less than 24 hours. It is more abrasive because the sand is not fully bonded with the cement and coarse aggregate.
Chain life is decreased in both the chassis joints and diamond segments. A harder segment bond is desired for abrasive
conditions.
6.3 OPERATIONAL FACTORS AFFECTING CHAIN LIFE
There are eight operational factors affecting chain life which are summarized as follows:
1.
Water Flow Rate—The water flow rate to the chain is a critical factor in both the segment life and chain life. Water is the
system coolant and flushing agent for grit and particulate. It is important to note that the required water flow is the flow to
the chain and not the flow from the hose or water supply. Water leaks or plugged water orifices may actually decrease the
flow to the chain. The minimum water flow to the chain is 2.5 gpm from the guide bar at a pressure between 50-160 psi.
The recommended pressure for most applications is between 80-100 psi. Higher water pressures are desired for abrasive
conditions.
Insufficient water supply decreases chain life two (2) ways:
a.
b.
Chassis wear or “stretch” is increased, resulting in wearing out of the chassis rivets and/or drive link holes.
Segment bond wear is increased due to the abrasive slurry not being flushed out.
19
2.
Mode of Cutting
Plunge vs. Slab—Plunge cutting increases diamond segment wear because both impact and loading increase. Depending on
the ratio of plunges and the cutting depth, chain life can be reduced.
Buried nose vs. Through cut—When cutting with the bar nose buried in the cut, the slurry increases the wear on both the
chain and segment. It can be expected that both the segment life and chain life will be decreased.
3.
Direction of Cutting (Horizontal vs. Vertical)—Cutting horizontally decreases chain life. When cutting vertically (up or
down), feed load is applied mainly to the top diamond surface. Cutting horizontally applies downward load to the diamond
top and gravitational load to the diamond side from the tool weight. This side load creates non-uniform side wear on the
segment and can eventually cause side clearance loss.
4.
Cutting Technique (Impact vs. Smooth)—Impacting the cutting surface with the chain decreases the chain life. Impact
forces create excessive stress and wear in the chain components. Impact forces also dull the diamond segments, decreasing
the segment life and performance.
5.
Rotational Speed—Optimum cutting performance is achieved when operating with a hydraulic input of 8 GPM (4100 RPM).
Operating with a hydraulic input of less than 8 GPM will give less than optimum performance, whereas a hydraulic input in
excess of 8 GPM will decrease the life of both the segment and chain.
6.
Excessive Feed Force—Excessive feed force dulls the diamond segments, decreasing the segment life and performance.
7.
Chain Tension—Improper chain tension increases chassis wear in the rivets and/or drive link holes, possibly “stretching” the
chain beyond its usable pitch diameter.
8.
Improperly Maintained Bar and/or Drive Sprocket—Improperly maintained bar rails, nose sprocket, and/or drive sprocket
can increase the chain chassis wear, causing premature “stretching” and possibly uneven segment wear.
6.4 CHAIN END-OF-LIFE MODES
There are three different end-of-life conditions that can occur, depending on a specific combination of factors as discussed in
Sections 6.2 and 6.3. These conditions are as follows:
1.
Wear Out of Diamond Top Surface—This condition occurs when the diamond segment height is worn down to about 1/16”
(0.0625” or 1.5 mm) remaining.
2.
Loss of Diamond Side Clearance—This condition occurs when the diamond side surfaces are worn at a rate higher than the
diamond top surfaces. The resulting end-of-life condition is a diamond segment width of about 0.187” (4.7 mm).
3.
Wear Out of Chain Chassis—This condition is characterized by worn chain rivets and chain drive link holes, and appears as
“stretch.” This mode leaves a portion of the diamond segment unused. Excessive “stretch” is evident when the drive tangs
can come completely out of the groove after tensioning the chain mounted on the bar.
