Machine Operation - Operating Procedures
Before Starting The Engine
The Warning alarm should sound and the Engine
Stop & Engine Warning / Wait lights should flash.
If not, turn the ignition key to the “OFF” position
and have the system warning lights and warning
alarm checked and repaired before operating
the machine.
You must read and understand the safety signs
and safety information found in Section 2 of
this manual before performing any operation or
maintenance procedures.
2) Check to see if the Wait \ Engine Warning light
is lit. If the Wait light is lit, wait until it goes off
before starting. See Figure 1 - Item #8.
General Pre-Start Inspection
Always perform a general pre-start inspection
before starting the machine.
Check around and under the machine for oil or
coolant leaks, worn or damaged components and
loose bolts or fasteners. Clean up accumulated
debris, especially in the engine, pump and exhaust
areas where fires are most likely to start.
Check engine oil, hydraulic oil, coolant and fuel
levels. When in cold weather conditions, make
sure the engine oil and hydraulic oil are the correct
viscosity, the coolant is the correct mixture and
the diesel fuel is the proper grade for cold weather
operation. Refer to the “Lubricant & Fill Capacities”
chart in Section 3.1.
See “Daily Machine Walk-Around Inspection”
in Section 3.1 for detailed daily inspection
Engine Starting Procedure
When the engine Wait light is "Lit" the engine is
preparing itself for startup. It is important to wait
until this light is off before starting.
(Cummins engines only) When temperature is
below 32 F (0 C) the Wait Light will shut off for a
moment and turn back on again. At this time the
internal intake grid heater is activated to aid in
engine startup. Wait until the light has turned off
for the second time before starting.
3) Turn the ignition key to the “START” position.
If the engine does not to start after 15-30
seconds of cranking, return ignition key to the
“OFF” position and wait before trying to start
engine again to allow the starter to cool down.
4) When the engine starts, release the ignition

Machine Operation - Operating Procedures
Cold Weather Starting
(Below 32oF (0oC))
When in cold weather conditions, make sure
the engine oil and hydraulic oil are the correct
viscosity, the coolant is the correct mixture and
the diesel fuel is the proper grade for cold weather
operation. Refer to the “Lubricant & Fill Capacities”
Section 3.1.
The engine starting procedure is the same for cold
weather conditions. The machine may also be
equipped with optional equipment that make starting
the machine in cold weather easier.
Additional pre-heating equipment may be required
when starting the machine in cold weather
conditions below 0 F (-18 C). Such equipment
could include an engine block heater, Espar Preheater, or Engine Wet Kit. See instructions in this
section on Optional Heaters.
Engine Shut-down
Figure 2: Master Disconnect
Engine Break-in Period
A gradual engine break-in period is recommended.
During the first 50 hours of operation, run the
engine at moderate speeds and avoid prolong
Check the system monitoring gauges
frequently, paying particular attention to the
following gauges and warning lights: See Figure 1.
1) Hydraulic Oil Temperature
Stopping the engine immediately after it
has been working under load can result in
overheating and accelerated component wear.
Allow engine to cool down while running at low
idle before shutting down.
2) Engine Oil Pressure
3) Engine Water Temperature
6) Return Filter Warning Light
1. With the machine parked, run the engine at low

Machine Warm-Up Procedure
3. If the machine is to be left un-attended, such
as overnight, switch off the master electrical
disconnect or disconnect the positive (+)
battery cable. See Figure 2.
Operating the machine at full speed when engine
and hydraulic oils are cold could cause serious
damage to the engine or hydraulic pumps and
Engine Idling
Avoid unnecessary engine idling. Long idling
periods can cause rapid wear of engine parts.
Maintain 1000 rpm or more if prolonged idling is
When the outside air temperature is below 32 F
(0 C). Follow these instructions to help warm and
breakup the engine and hydraulic oils before trying
to operate the machine at full speed.
Machine Operation - Operating Procedures
1.) Run the engine at idle for at least 5 minutes to
allow the engine to warm-up before increasing RPM
or operating hydraulic functions. Always monitor all
gauges and warning lights at this time.
5. Always shut down engine before leaving machine.
If machine must be left running use extra caution
when parking machine. Make sure machine is
parked far away from people and obstacles
If optional charge heater is equipped on your
machine you may turn it on at this time. Always
keep a close watch on machine when using
charge heater. Never turn on charge heater and
leave the machine unattended. Always cycle the
machine hydraulics at a low RPM after using the
Charge Heater.
Parking: Freezing Conditions
In freezing conditions, park the machine were it
will not freeze into the ground.
2.) After engine has warmed slowly operate the
Grapple or Clamp function. Wait a few seconds
between the open and closing for recovery. You may
slowly increase the engine RPM as the hydraulic
temperature begins to rise.
DO NOT attach pulling chains around the axles
if attempting to free the machine when stuck
or frozen into the ground. Damage to the
axles may result. Use only the towing points
3.) When hydraulic oil temperature has reached
50 F (10 C) you may now run the machine at full
When parking the machine in freezing conditions,
planks or forest debris can be placed under the
wheels to prevent them from freezing into the
ground. This is especially important when chains
or tracks are installed around the wheels and the
boom cannot be used to help free the machine.
Also place planks or forest debris under the loader
bucket or cutting attachment to prevent it from
freezing into the ground.
Parking The Machine
When parking the machine, select a spot where
the ground is level. Do not park on a hillside or
any incline.
Working in Wet And Muddy
Ground Conditions
When freezing conditions are expected, do not
park machine in loose or wet soil which could
freeze around the wheels or in the wheel chains
or tracks when installed.
1. Select a level spot to park the machine. If it is
necessary to park on an incline, the wheels must
be blocked securely.
The drive shaft u-joints and carrier bearings, axle
drive shaft yoke bearings, and axle articulation
bearings should be lubricated daily if the machine is
working in very damp conditions or the drive shaft
is submerged in water or mud during operation.
Greasing daily will help keep water out of these
Important Towing
After each day/shift’s operation dirt and debris
should be cleaned from the wheels and tracks
when installed.
2. Reduce engine speed to low idle.
3. Lower booms and attachment and place them
securely on the ground.
4. Turn Auto Parking Brake switch "ON" before
exiting operator's cab.
Machine Operation - Operating Procedures
Serious personal injury or death could result
when towing a disabled machine incorrectly.
Contact your TimberPro dealer or the factory
before beginning any towing procedure.
Block the wheels to prevent movement
before releasing the parking brakes
or disconnecting the driveshafts.
machine can roll free if the wheels are not
towing machine, for a disabled machine stuck in
mud or when towing on a grade.
Attach towing cable to towing hook found on either
end of the machine.
Follow the recommendations below to
properly perform the towing procedure.
DO NOT use a chain for pulling. A chain link can
break causing possible personal injury. Use a wire
rope cable with loop or ring ends. Use an observer
in a safe position to stop the pulling procedure if
the cable starts to break or unravel. Stop pulling
whenever the pulling machine moves without
moving the towed machine.
Relieve the hydraulic tank and line pressure
before any disassembly.
Even after the machine has been turned off,
the hydraulic oil can still be hot enough to
burn. Allow the hydraulic oil time to cool
before draining.
Keep the tow line angle to a minimum. DO NOT
exceed a 30 angle from the straight ahead
Quick machine movement could overload the tow
line or bar and cause it to break. Gradual and
smooth machine movement will work better.
Tow the machine only in an emergency situation
or if there has been an engine failure or a major
failure that requires the machine to be moved
to service facility.
Normally, the towing machine should be as large
as the disabled machine. Make sure that the
towing machine has enough brake capacity, weight
and power to control both machines for the grade
and distance involved.
To provide sufficient control and braking when
moving a disabled machine downhill, a larger
machine or additional machines connected to
the rear could be required. This will prevent the
disabled machine from rolling uncontrolled.
If there has been a hydraulic failure of the wheel
drive pump, wheel drive motor, or a mechanical
failure of the transfer case, it is much better
to replace the component without towing the
machine. Towing a machine with a failed wheel
drive pump or motor will likely contaminate other
major hydraulic components in the hydrostatic
wheel drive circuit while towing.
A towed machine, when loaded, must be
equipped with its own brake system operable from
the operator’s compartment.
Only tow a disabled machine a short distance
and no faster than 1.2 mph (1,9 km/h). Always
haul the machine if long distance moving is
Towing Machines That Are
Shielding must be provided on the towing machine
to protect the operator if the tow line or bar should
DO NOT allow an operator on the machine being
towed unless the operator can control the steering
and/or braking.
Before towing, be sure the tow line or bar is in good
condition and has enough strength for the towing
situation involved. Use a towing line or bar with a
capacity at least 1.5 times the gross weight of the
Use the following procedure only if there has been
no hydraulic failure of the wheel drive pump, wheel
drive motor, or in case of an emergency.

Ready The Machine For Towing
Machine Operation - Operating Procedures
1. Review all Important Towing Information on 4.3.4
before beginning the towing procedure.
2. Block all wheels to prevent movement of the
machine while disengaging the parking brake
and disconnecting the drive shafts.
The parking brake must be released to tow the
a disabled machine. The best way is to use the
manual parking brake releases provided on
each axle differential.
3. Using the 3/4” wrench, remove the bolts securing
the access covers over the axle parking brake
housings on tandem axles.
Figure 5: Axle Parking Brake Release
4. Use the 24mm wrench to access the manual
parking brake releases on the tandem axles.
See Figure 3. The release screws are provided
behind the parking brake housing covers.
5. With the wheels blocked, use the 18mm
wrench to turn the parking brake manual release
screws clock-wise all the way in to release the
parking brake. Do this for both the front and rear
axles. See figure 5.
6. With the wheels blocked, use the 3/4” wrench to
disconnect the drive shafts at the front and rear
NOTE: DO NOT disconnect the drive shafts
anywhere but at the axle yokes. Disconnecting the
driveshaft elsewhere may damage the driveshaft
when the axle rotates during towing.
7. Clean away all debris from the area around the
steer cylinder hose connections. Pack the area
with plenty oil-absorbant rags to catch oil spills.
Figure 3: Tandem Axle Parking Brake Release
TimberPro 630 machines have a single axle that
contains four bolts with jam nuts to release the
parking brakes. See figure 4.
NOTE: As the disabled machine follows the towing
machine, oil will be forced out of the steer cylinders
during articulation.
8. Using the 7/8” and 15/16” wrenches, disconnect
the hoses to both steer cylinders. Plug all hoses
but leave the fittings uncapped. This will allow
the machine to articulate and follow the towing
machine without engine power.
9. Connect the towing line or bar. Be sure the towing
machine is suitable for towing the disabled
machine and has the braking power for itself and
the disabled machine.
10. Remove blocking from the wheels.

After Towing
1. Block all wheels to prevent movement of the
machine while the parking brake is being set
and repairs are being made.
2. If the manual parking brake release screws were
used, turn them out counter-clockwise to set the
parking brake at both axles.
A warm water circulation kit (wet kit) is available
to preheat the engine block before starting. The
wet kit allows an external warm water source (a
properly equipped service vehicle, portable propane
water heater, etc.) To be circulated through the
machine’s cold engine for easier starting. The wet
kit connections are in theThe mating connectors
required to make the connection are available from
your TimberPro dealer (PN 17307F) See Figure 6.
3. Perform necessary repairs to the machine.
Charge Heater
After Repairs Have Been Made
A wheel drive charge oil heater block is available as
an option for helping to speed-up hydraulic system
warming in colder climates. The Charge Heater uses
wheel drive system charge oil and forces it across a
relief warming the oil and recirculating it back to the
hydraulic tank. The Charge Heater is set to shut off
automatically at 70 F.
1. With the wheels blocked and the parking
brake set, re-connect the drive shafts at the front
and rear axles.
2. Remove blocking from the wheels.
3. The machine is now ready for testing and normal
The Charge Heater control switch is located on the
left joystick control pad and is opposite the Arming
Switch. See Section 4.2 on machine controls.
Optional Heaters
Espar Pre-Heater Control
The Espar Pre-Heater is an optional diesel powered
pre-heater that warms the engine coolant and the
hydraulic oil.
The Espar Pre-heater contains a programmable
control module that can be programed to
automatically turn on the pre-heater.
The Espar Pre-Heater will get extremely hot.
Always clean all debris and flammable fluids out
from around the heater and the heaters exhaust
before use. Always use extra caution when
programing heater to turn on when no one is
around the machine to supervise.
