EXTENSION CORDS

Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept the tool's plug.

When using a power tool at a considerable distance from the power source, use an extension cord heavy enough to carry the current that the tool will draw. An undersized extension cord will cause a drop in line voltage, resulting in a loss of power and causing the motor to overheat. Use the chart provided below to determine the minimum wire size required in an extension cord. Only round jacketed cords listed by

Underwriter's Laboratories (UL) should be used.

Length of Extension Cord Wire Size (A.W.G.)

Up to 25 feet 14

26-50 feet 12

When working with the tool outdoors, use an extension cord that is designed for outside use. This is indicated by the letters WA on the cord's jacket.

Before using an extension cord, inspect it for loose or exposed wires and cut or worn insulation.

CAUTION:

Keep the cord away from the cutting area and position the cord so that it will not be caught on material, tools, or other objects during cutting.

GROUNDING INSTRUCTIONS

In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This tool is equipped with an electric cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances.

Do not modify the plug provided. If it will not fit the outlet, have the proper outlet installed by a qualified electrician. Improper connection of the equipment-grounding conductor can result in a risk of electric shock. The conductor with insulation having an outer surface that is green with or without yellow stripes is the equipment-grounding conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment-grounding conductor to a live terminal.

Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether the tool is properly grounded.

Repair or replace a damaged or worn cord immediately.

This tool is intended for use on a circuit that has an outlet like the one shown in Figure 1. It also has a grounding pin like the one shown.

ELECTRICAL CONNECTION

Your Cut-Off Machine is powered by a precision built electric motor. It should be connected to a power supply that

is 120 volts, 60 Hz, AC only (normal household current).

Do not operate this tool on direct current (DC). A substantial voltage drop will cause a loss of power and the motor will overheat. If the machine does not operate when plugged into an outlet, double check the power supply.

POWER SUPPLY

Before operating your cut-off machine, check your power supply and make sure it meets the requirements listed on the tool’s data plate. A substantial voltage drop will cause a loss of power and machine overheating.

Common causes of power loss and machine overheating are insufficient extension cord size and multiple tools operating from the same power source.

ADJUSTMENTS

TO ADJUST DEPTH STOP

See Figure 14.

The depth stop limits the wheel's downward travel. It allows the wheel to go below the machine base enough to maintain full cutting capacities.

The adjustable depth stop is a bolt threaded into the pivot bracket at the rear. To adjust the depth stop use the arbor wrench supplied to raise or lower the depth stop bolt.

The depth stop is factory set to provide maximum cutting capacity for the 14 in. (356 mm) abrasive wheel provided with your cut-off machine.

When the diameter of the wheel has been reduced due to wear, it may be necessary to adjust the depth stop to provide maximum cutting capacity. When a new abrasive wheel is installed, it is necessary to check the clearance of the wheel to the machine base support.

WARNING:



n Loosen the depth stop bolt.

n The depth stop is lowered by turning the depth stop bolt clockwise and raised by turning the bolt counterclockwise.

n By pressing down on the machine arm, lower the wheel and check clearance and maximum cutting distance

(distance from adjustable stationary vise where wheel enters) to front of machine base slot.

n Adjust if necessary.

n Tighten the depth stop bolt with the arbor wrench provided.

CAUTION:

Do not start your cut-off machine without checking for interference between the wheel and the machine base support. Damage may result to the wheel if it strikes the machine base support during operation of the machine.

MAINTENANCE

WARNING:

When servicing, use only identical RIDGID replacement parts. Use of any other part may create a hazard or cause product damage.

GENERAL

Avoid using solvents when cleaning plastic parts. Most plastics are susceptible to damage from various types of commercial solvents and may be damaged by their use. Use a clean cloth to remove dirt, carbon dust, etc.

CAUTION:

Do not at any time let brake fluids, gasoline, petroleum-based products, penetrating oils, etc. come in contact with plastic parts. They contain chemicals that can damage, weaken or destroy plastic.

BRUSH REPLACEMENT

See Figure 15.

Your cut-off machine has externally accessible brush assemblies that should be periodically checked for wear.

Proceed as follows when replacement is required:

ASSEMBLY

LUBRICATION

All of the bearings in this tool are lubricated with a sufficient amount of high grade lubricant for the life of the unit under normal operating conditions. Therefore, no further lubrication is required.

WARNING:

Keep extension cords away from the cutting area and position the cord so that it will not get caught on materials, tools, etc., during cutting operation.

WARNING:

Check extension cords before each use. If damaged, replace immediately. Never use tool with a damaged cord since touching the damaged area could cause electrical shock resulting in serious injury.

WARNING:

Always wear safety goggles or safety glasses with side shields during power tool operation or when blowing dust. If operation is dusty, also wear a dust mask.

WARNING:



n Remove brush cap with a screwdriver. Brush assembly is spring loaded and will pop out when you remove brush cap.

n Remove brush assembly.

n Check for wear. Replace both brushes when either has less than 1/4 in. length of carbon remaining. Do not replace one side without replacing the other.

n Reassemble using new brush assemblies. Make sure curvature of brush matches curvature of motor and that brush moves freely in brush tube.

n Make sure brush cap is oriented correctly (straight) and replace.

n Tighten brush cap securely. Do not overtighten.

WARNING:

To ensure safety and reliability, all repairs — with the exception of the externally accessible brushes

— should be performed by a RIDGID Authorized

Service Center.
