General Safety Information
TimberPro’s policy is to produce products that are
safe and reliable. However, even when using well
engineered equipment, there will always be an
element of risk in heavy equipment operation.
Most accidents involving heavy equipment
operation, maintenance or service result from
failure to follow basic safety rules and precautions.
Study all the safety messages carefully, remember
them and apply them when operating, maintaining
or servicing equipment.
“Safety Alert” Symbol
Identifies that a safety hazard exists. Failure
to follow a WARNING safety message
can result in death or serious personal
injury if proper precautions are not taken.
Identifies that a safety hazard exists. Failure
to follow a CAUTION safety message can
result in personal injury or equipment damage
if the proper precautions are not taken.
The signal words DANGER, WARNING and
CAUTION are used to identify personal safety
hazards and some equipment cautions. The
signal word NOTICE is used to identify
hazards that may damage equipment or its
components.
Figure 1 - Safety Alert Symbol
The “Safety Alert” symbol is used throughout
the manual text and on the machine to
indicate important personal safety measures and
equipment cautions. Carefully read, understand
and follow these instructions to prevent hazardous
situations, possible injuries to personnel or damage
to equipment.
Understanding Signal Words
In this manual and on the safety decals installed
on the machine, the “Safety Alert” symbol is always
accompanied by a signal word to identify the hazard level. Understand the signal words DANGER,
WARNING, and CAUTION.
Identifies the most serious safety hazards.
Failure to follow a DANGER safety message
would result in high probability of death or
serious personal injury.
Follow procedures as outlined to avoid damage
to equipment or its components as a result of
misuse or improper procedures.
The Careful Operator
A careful operator studies, remembers and applies
the basic safety rules and all safety messages found
in the manuals and on the equipment being operated, maintained or serviced. This person also has
the required training, skills and tools to operate the
equipment and/or perform the required maintenance
and service procedures.
TimberPro cannot anticipate every possible
circumstance where a potential hazard may exist.
Therefore, the safety messages and equipment
cautions found in the manuals and on the
machine are not all inclusive. If an operating
technique, maintenance or service procedure, tool,
etc... not specifically recommended by TimberPro is
used, it is your responsibility to insure it is safe for
yourself and others. You should also be sure the
machine will not be damaged or made unsafe by
the operation, maintenance procedures or service
procedures you choose.
WHEN IT COMES TO SAFETY, NOTHING WILL
EVER REPLACE A CAREFUL OPERATOR.

Disc Saw Safety Information
It is essential that all operators of the disc-felling
head become familiar with all aspects of its correct operation.
1. Remember at all times that the disc saw blade,
at operational speed carries a tremendousamount of stored energy. Tooth tip speeds can be
up to 17000 ft/min. Flying chips or other debris
can cause serious injury. Do not approach the
felling head unless the disc saw blade has come
to a complete stop, and the engine has been
shut down.
2. During operation of the disc felling head, all
personnel not in the machine should remain at
least 300’ away and never cross in front of the
saw opening.
Do not bend or install bent or damaged hydraulic
hoses and tubelines.
Do not strike hydraulic hoses or tubelines.
Be sure all hose clamps, guards and protective
wrapping is installed correctly to prevent vibration
and rubbing which could lead to hose failure.
00009
3. All observers should stand on the opposite side
of the disc rotation. In other words the opposite
side of the chip path from the primary opening.
4. As debris is always being released from the
saw-housing opening, the operator must remain
in the cab until blade has stopped rotating completely.
5. Saw operation speed should be respected. Do
not exceed maximum allowable r.p.m. Wait until
disc saw achieves full speed (see saw motor
RPM settings) before proceeding to cut.
6. Inspect saw blade at start of every shift and,
periodically during the shift. See daily inspection
information.
7. Shut saw off immediately if an imbalance occurs.
Imbalances can result from a bent disc, loose or
lost parts and can be indicative of a serious
problem. Inspect all parts of saw blade prior
to restarting. Do not operate saw blade in any
unbalanced condition.
Hydraulic oil under pressure can penetrate body
tissue causing serious injury and possible death.
When troubleshooting a hydraulic system for
leaks, always use cardboard or other material as
a deflector. DO NOT USE YOUR HANDS.
If you are injected with hydraulic oil or any other
fluids, seek treatment by a doctor familiar with
this type of injury immediately.
Operation, Maintenance, and Parts
8. Do not work on blade or head while machine
is running, except when performing required
hydraulic checks.

General Maintenance
Before performing any maintenance or
service work, lower the attachment to the
ground and shut off the engine. Turn off any
master shut-offs and do not allow personnel

after a few hours of use and then again every
200 hours. There will be one ring of thirty (30)
3/4" allen bolts (item #10 below) that connect
the mount to the head and get torqued to Torque
to 377 ft.lDS (512 Nm) and one ring of standard
bolts (item #9 below) that secure the bearing to

occur. Fill bearing cavities until grease begins to
expel from relief ttings.
Figure 2: Saw Drive Grease Fittings
Note that there is a plug at the center of the saw
disc mounting ange. This is an access hole for
a grease zerk that allows grease to reach the
splined adapter between the motor and shaft.
This should be greased every 500 hours.
Figure 1: Boom Adapter Mounting Bolts
Before start-up, make sure the saw head has
been greased. Every pin joint will have a grease
zerk. Each cylinder end will also have a grease
zerk.
Grease the saw drive daily at the beginning of
each shift (two separate cavities). Ensure grease
relief tting are functional. If relief ttings are not
functioning properly, damage to shaft seals may

3. Check saw retaining bolts on lower ange
once at a 100 hour inspection, and every
2000 hours after that for correct torque. (320

4. Inspect and Clean debris between saw
blade, housing and guard.
5. Check disc housing guarding for damage
and blade contact. Make necessary repairs
when needed.
6. Check saw head regularly for cracks. Repair
any damage.
7. Inspect hydraulic hoses, ttings and cylinders for damage or wear. Replace or repair
if necessary.
8. Inspect cutting teeth for damage. Make sure
the teeth are in good shape and that all
mounting hardware is secure. Never mix dif-

Operating Instructions
NOTE: When rst becoming familiar with the
disc saw felling head, tilt the head forward to the
vertical position when the saw is being started
or stopped.
saw head. This is done by tilting the head
using the "tool tilt" function into the direction
you would like to place the trees. Then opening all clamp arms to relase the trees.
7. When your nished using the disc saw turn
off the disc saw pump. Then either position
the disc saw in a place that is safe and free
of people or animals and monitor the disc
until it comes to a complete stop. You may
also use a near by stump to stop the disc.
Make sure and slowly pust the disc into the
stump until the disc stops.
1. Start the saw rotation, open accumulator
arms, open top grab just before you are
ready to cut a tree.
2. Tilt the head to the upright position and move
toward the rst tree.
3. As the cut is being made, the upper clamp
arms should begin to close, but should not
be completely closed until the cut is completed.
NOTE: It is important not to fully clamp the tree
until after the cut is complete. Clamping the tree
before the cut is complete, may cause damage
to the stem and unnecessary binding or stalling
down of the saw blade.
4. Once the tree is completely severed, the
head should be immediately raised off the
stump. This is important to avoid stalling
down of the saw blade.
NOTE: When using a stump to stop the disc
make sure and push the disc into the stump using the same procedure as when your cutting a
tree. Never push downward on the stump with
the bottom of the disc. This can cause damage
to the disc and disc drive system. See gure 3
00481
NOTE: It is obvious that a smooth and continu-
ous feed speed of the saw will prevent binding
or stalling of the saw blade. Speed of cut must
be related to tree size and species.
5. When cutting smaller trees, at this time the
operator would then close the lower "accumulation" arms. This would ready the the
disc saw for the next cut.
NOTE: The lower "accumutlation" arms are
used to hold the smaller trees when opening the
upper arms to make the next cut.
6. Once done making a cut or multiple cuts, the
trees will be need to be dumped from the disc
Operation, Maintenance, and Parts
Figure 3: Correct Stopping Procedure
Never leave a disc saw still spinning and unattended. Even after a disc saw has been
shut off the disc will continue to spin with
enough force to cause injury or harm. Never
try to manually stop a disc that is spinning.

Saw Motor RPM Adjustment
Ensure that the 100 mm (3.94 inch) long saw
speed adjustment screw (see gure 4) is turned
in until 19 mm (.75 inch) of the stud protrudes
beyond the jam nut. (This prevents over speeding the saw at initial start-up)
Install 5000 p.s.i. pressure gauges at saw valve
test port and at “G” port (# 4 ORB style) and
“M” port (# 6 ORB style see gure 5) of saw motor. Block saw blade rotation with pin in base
assembly saw housing.
With engine at full throttle adjust saw circuit relief valve to read 3800 psi at “G” port on saw
motor pressure inlet block.
Figure 4: Saw Drive Motor RPM
With saw free to rotate turn saw circuit ON and
bring engine to full throttle. Turn saw speed
adjustment screw out until saw speed is 1139
r.p.m. Lock jam nut on saw speed adjusting
screw.

Turn the “begin of stroke” adjustment screw out
until the gauge in the “M” port reads 0 psi.
Then slowly turn the “begin of stroke” adjustment screw in until the pressure gauge in the
“M” port reads 1800-2000 psi. Lock jam nut on
adjusting screw.
Reset the pump pressure to recommended carrier specs. (4000 PSI)
