Maintenance Schedule - Greenlee 42247 Operation, Service And Parts Instruction Manual

Maintenance Schedule

Inspect saw chain every operating day. Do not
operate tool with a damaged or worn saw chain.
An improperly sharpened, dull, worn or damaged
saw chain increases the risk of kickback and
pushback.
Failure to observe this warning could result in
severe injury or death.
Inspect hydraulic hoses and couplings every
operating day. Repair or replace if leakage,
cracking, wear, or damage is evident. Damaged
hoses or couplings can fail resulting in injury or
property damage.
Daily:
1. Wipe all saw surfaces clean of grease, dirt and
foreign material.
2. Inspect the saw chain mounted on the saw before
and frequently during use. Chain must be properly
sharpened and have no worn or damaged compo-
nents. AN IMPROPERLY SHARPENED, DULL,
WORN AND/OR DAMAGED CHAIN INCREASES
THE RISK OF KICKBACK.
3. Inspect the hydraulic system hoses and fittings for
signs of leaks, cracks, wear, or damage. Replace if
necessary.
4. Check the saw chain tension before and frequently
during use. Adjust as often as necessary. LOOSE
CHAINS INCREASE THE RISK OF KICKBACK.
5. Check the automatic chain oiler before and fre-
quently during use. The chain will give off a fine
spray of oil at the guide bar nose if the oiler is
working properly. Insufficient lubrication can ruin
the saw chain and/or guide bar.
6. To prevent contamination, always install dust caps
over the hydraulic ports of the chain saw when
disconnected.
Monthly:
Perform a detailed inspection of the system hoses and
fittings as stated in Appendix A - S.A.E. Standard
J1273, May 1986. Replace the hoses and/or fittings if
necessary.

Automatic Chain Oiler
The automatic chain oiler provides a constant supply of
oil to lubricate the guide bar and chain whenever the
saw is operating. A metering screw controls the amount
of oil supplied. The metering screw is preset at the
factory, but may be adjusted to increase or decrease the
oil output volume. Insufficient lubrication can ruin the
saw chain and/or guide bar.
Checking Automatic Oiler Setting
1. Operate the chain saw without cutting any wood.
Notice the guide bar nose while operating.
A. If the saw chain gives off a fine spray of oil, the
oiler is working properly.
B. If the saw chain does not give off a fine spray of
oil, the oiler may need to be adjusted.
Note: Before adjusting the automatic oiler output,
always make sure the oil passage in the base of
the guide bar is cleaned first. If oil drips off the
saw head, sprocket cover and/or base of the bar,
this is an indication of a plugged oil passage in
the bar.
Adjust the Automatic Oiler Setting
(See Figures 1 and 2)
1. STOP THE POWER SOURCE.
2. Turn the metering screw (11) clockwise to decrease
or counterclockwise to increase oiler output flow.
Limit adjustment to 1/2 turn at a time.
3. Start the power source. Recheck the automatic oiler
setting.
