Certain maintenance operations or machine adjustments
require specialized knowledge and skill. Attempting to
perform maintenance operations or adjustments without
the proper knowledge, skills or training could result in
equipment damage or injury to personnel. If in doubt,
consult your dealer.
WARNING — Accidental Starting Hazards
Accidental starts can cause severe injury or death!
ALWAYS place the ON/OFF switch in the
OFF position.
Engine and muffler surfaces can get HOT!
Allow to cool before servicing.
ALWAYS ensure saw is SECURELY
placed on appropriate blocks or jackstands
when performing maintenance requiring the
saw to be elevated.
CAUTION — Clean up spills
Avoid slips and falls!
Clean up all engine oil, hydraulic oil, and
diesel fuel spills immediately.
When performing maintenance operations on
the saw or engine, follow all safety messages
and rules for safe operation stated here and
at the beginning of this manual.
See the engine manufacturer’s manual supplied with your
machine for appropriate maintenance schedule and
troubleshooting guide for problems.
Maintenance Schedule
Daily (8-10 Hours)
1. Check fluid levels in engine and reservoir; fill as
necessary.
2. Visually inspect for wear and damage.
3. Visually inspect for engine leaks.
4. Check or replace the engine air filters as necessary.
5. Check operation of emergency stop button.
Monthly (125-150 Hours)
1. Change hydraulic oil and filter (First 125 hours, then
every 250 hours),
2. Change engine oil and filter.
3. Check the tension and integrity of the drive and
hydraulic pump V-belts (see Page 45).
Yearly (500 Hours)
1. Replace fuel filter cartridge, v-belt, and intake air
cleaner.
2. Check fuel lines for leakage.
3. Check battery cables and connectors.
4. Check engine monitoring and warning system.
AIR CLEANERS (DAILY)
The saw utilizes both a primary air filter and a safety air
filter (Figure 36). The air filter restriction light, (Figure 35,
Item A) on the engine status indicator (Figure 35, Item B),
will illuminate when the filter is plugged.
Empty the dust discharge valve daily and clean the
discharge slot from time to time (Figure 36).
While the air filters should be checked daily and replaced
when necessary, there is no need to “over-service” the air
filters. That is, they require no cleaning and do not require
the use of oil. If the primary filter becomes clogged, simply
replace it.
