MAINTENANCE (SAW)
General maintenance practices are crucial to the
performance and longevity of your saw. The extreme
environments of sawing operations require routine cleaning,
lubrication, belt tensioning, and inspection for wear and
damage
The following procedures devoted to maintenance can
prevent serious saw damage or malfunctioning.
Removing or installing blades
Adjusting front or rear pointers
Lubricating any components
Removing engine mounting bolts
Inspecting, adjusting or replacing drivebelt, spindle,
spindle bearings or any engine part
Removing blade or belt guards
NOTICE
See the engine manual supplied with
your machine for appropriate engine
maintenance schedule and troubleshooting
guide for problems.
DANGER
Some maintenance operations may
require the engine to be run. Ensure that
the maintenance area is well ventilated.
Exhaust contains poisonous carbon
monoxide gas that can cause of unconsciousness and
may result in DEATH.
WARNING
NEVER place hands or feet inside the belt
guard or blade guard while the engine is
running.
Before servicing or inspection, ALWAYS
park the saw on a level surface with the
blade removed, and the handlebar Engine
ON/OFF switch and Engine ON/OFF
switch in “OFF” position.
Front Pointer Adjustment
The front pointer wheel has been set at the factory. Use
these procedures only if the pointer is suspect of being
out of alignment.
1. Chalk out a straight line on the prepared slab or cutting
surface.
2. Use a straight-edge or level by placing it flat against
the blade.
3. Adjust the front pointer wheel so it just touches the side
of the straight-edge or level.
4. Remove the straight-edge or level.
5. Position the front pointer and blade directly over the
chalk line.
6. Start the saw and lower the blade onto the chalk line.
7. Begin cutting and make sure the blade follows the chalk
line as closely as possible.
8. The pointer should follow the chalk line as well. If it does
not, adjust the pointer by loosening then tightening the
jam nuts on the pointer until the pointer follows the
same path as the blade.
Chassis Lubrication
Spindle Bearings - Two zerk fittings are located up under
the lower-front of the saw. Lubricate before daily use.
Use a good quality extreme pressure grease. Check
and lubricate more often if unit is under heavy use. Do
not overfill bearings. Overfilling can damage the grease
seals. This can result in bearing exposure to dirt and
contaminants which can then shorten the life of the
bearings. Excess grease can also drip onto the cutting
surface.
General Cleanliness
Clean the machine daily. Remove all dust and slurry build
up. If the saw is steam cleaned, ensure that lubrication is
accomplished AFTER steam cleaning operations.
CAUTION
ALWAYS allow the engine to cool
before servicing. NEVER attempt any
maintenance work on a hot! engine.
