SCHEDULE
Use this schedule to maximize the tool's service life.
Notes:
Keep all decals clean and legible. Replace decals when
necessary.
When disposing of any components (hydraulic hoses,
hydraulic fluid, worn parts, etc.), do so in accordance
with federal, state and local laws or ordinances.
Daily
1. Wipe all tool surfaces clean.
2. Inspect the entire chain before use. Tension and
sharpen the chain as instructed under Saw Chain
and Bar Maintenance. An improperly sharpened,
dull, worn or damaged chain increases the risk of
kickback.
3. Check the operation of the automatic oiler before
use as instructed under Checking and Setting the
Automatic Chain Oiler. An improperly set oiler can
accelerate the wear of the chain and bar.
4. Inspect the hydraulic hoses and fittings for signs
of leaks, cracks, wear or damage. Replace if
necessary.
5. Install dust caps over the hydraulic ports when the
tool is disconnected.
Monthly
1. Perform a thorough inspection of the hydraulic
hoses and fittings as described in publication
99930323, SAE J1273 (Hose and Hose Assemblies).
2. Perform the Bar Service procedure as described
under Saw Chain and Bar Maintenance.
3. Run the saw at full RPM and release the trigger.
Greenlee
Long-Reach Chain Saws
Make a note of the time it takes the chain to stop
completely (stop time). Compare to the stop times
recorded during previous months.
An increasing stop time indicates that the trigger
valve components are dirty or worn. Have the
tool cleaned or repaired by an Greenlee Utility
Authorized Service Center.
Annually
If required by your organization, have the tool inspected
by an Greenlee Utility Authorized Service Center.
CHECKING AND SETTING
THE AUTOMATIC CHAIN OILER
The automatic chain oiler provides a constant supply of
oil to lubricate the bar and chain whenever the saw is
operating. An adjustment screw controls the amount of
oil supplied.
Before adjusting the automatic oiler, clean the oil
passage in the base of the guide bar first. Oil dripping
off the saw head, sprocket cover or bar indicates that
the oil passage is plugged.
1. Run the saw at full rpm.
2. If the tip of the saw gives off a fine spray of oil, the
automatic oiler is working properly. If the saw does
not give off a spray of oil, adjust the oiler.
Note: For better results, hold saw so that the tip of
the saw blade is pointing toward a clean sheet of
paper or cardboard and run the saw at full rpm.
If the automatic oiler is working properly, the paper
or cardboard should soon show small droplets of oil.
3. Stop the hydraulic power source.
4. Fully tighten the oiler screw until it is seated.
Loosen 1/4 turn counterclockwise.
