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
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 haz-
ard 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.
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.
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 oper-
ated, 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.

Operation, Maintenance, and Parts
7
Run the engine only when it is required for
test or adjustment purposes.Always use the
proper tools for the job. Repair or replace
any broken or damaged tools, including
lifting equipment, immediately.
When servicing or replacing hardened steel pins,
use a brass drift or other suitable material between
the hammer and pin if it must be driven into the
pivot. Use safety glasses or other suitable eye
protection.
DO NOT make adjustments while the machine is
moving or the engine is running unless otherwise
specified to do so.
DO NOT change the pressure setting on any
hydraulic valve without authorized instruction.
Use all cleaning solutions with care. Avoid
breathing vapors and contact with eyes and skin
Keep all fuels and maintenance items in properly
marked containers.
Place all fuel or oil soaked rags, waste material,
debris and other flammable items in a properly
marked protective container stored in a safe place.
Inspect the machine for missing, unreadable or
damaged safety decals. Keep safety decals clean.
The maximum allowed air pressure used for
cleaning purposes should not exceed 30 psi
(205 kPa).
At operating temperature, the engine, exhaust
system components, cooling system
components and hydraulic system components
are HOT. Any contact can cause severe burns.
00017
Before performing maintenance or repairs on the

Pressure can be maintained in system circuits
long after the engine and pumps have been shut
down. Release trapped pressure in hydraulic,
fuel, and cooling system lines before performing
any maintenance or repair procedures.
00012
Hydraulic System
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.
Disc Saw Safety Information
It is essential that all operators of the disc-felling
head become familiar with all aspects of its cor-
rect operation.
1. Remember at all times that the disc saw blade,
at operational speed carries a tremendousa-
mount 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.
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 com-
pletely.
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.
8. Do not work on blade or head while machine
is running, except when performing required
hydraulic checks.
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.

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
in the cab
Re-torquing the boom Adapter Mounting
Bolts
The bolts of which hold the boom adapter
mounting bracket and bearing to the Disc saw
weldment should be re-torqued to 420 ft. lDS.
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
the mount and get torqued to Torque to Torque
to 420 ft.lDS (570 Nm).
Lubrication and Grease
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
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.
Disc Saw Daily Inspections
1. Check lower portion of shaft for grease leaks.
Repair damaged seals if required.
2. Check end shaft for end play. (.006” - .008”
allowance)
3. Check saw retaining bolts on lower ange
once at a 100 hour inspection, and every
2000 hours after that for correct torque. (320
lb./ ft)
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 cylin-
ders 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-
Figure 1: Boom Adapter Mounting Bolts

Operation, Maintenance, and Parts 10
ferent styles of cutting teeth. When teeth are
worn and damaged they should be replaced
as a matched set.
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.
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 com-
pleted.
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: 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 "accu-
mulation" 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
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 open-
ing 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.
NOTE: When using a stump to stop the disc
make sure and push the disc into the stump us-
ing 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
Figure 3: Correct Stopping Procedure
00481
Never leave a disc saw still spinning and un-
attended. 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 speed-
ing the saw at initial start-up)
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.
