Remove the cap and carefully pour approxi-
mately 2 oz. of bar and chain lubricant into the
bar lube reservoir.
Replace the cap and tighten securely.
Check and refill the bar lube reservoir every time
the pole saw is used.
NOTE:
Do not use dirty, used, or otherwise con-
taminated lubricants. Damage may occur to the
oil pump, bar, or chain.
CHAIN MAINTENANCE
See Figure 18.
WARNING:
Remove the battery pack and make sure the
chain has stopped before you do any work on
the saw to avoid accidental starting and pos-
sible serious personal injury.
For smooth and fast cutting, the chain needs to
be maintained properly. The following conditions
indicate that the chain requires sharpening:
Wood chips are small and powdery
Chain must be forced through the wood during
cutting
Chain cuts to one side
During maintenance of the chain, consider the
following:
Improper filing angle of the side plate can in-
crease the risk of a severe kickback.
Depth gauge (or raker clearance) setting de-
termines the height the cutter enters the wood
and the size of the wood chip that is removed.
Too much clearance increases the potential for
kickback. Too little clearance decreases the size
of the wood chip thus decreasing the chain's
cutting ability.
If cutter teeth have hit hard objects such as nails
and stones, or have been abraded by mud or
sand on the wood, have service dealer sharpen
chain.
HOW TO SHARPEN THE CUTTERS
See Figures 19 - 22.
Be careful to file all cutters to the specified angles
and to the same length, as fast cutting can be
obtained only when all cutters are uniform.
MAINTENANCE
Fig. 20
WARNING:
The saw chain is very sharp, always wear pro-
tective gloves when performing maintenance
to the chain to prevent serious personal injury.
Properly tension the chain prior to sharpening.
Refer to
Adjusting the Chain Tension
earlier in
this manual. Do all of your filing at the mid-point
of the bar.
Use a 5/32 in. diameter round file and holder.
Keep the file level with the top plate of the tooth.
Do not let the file dip or rock.
Using light but firm pressure, stroke towards
the front corner of the tooth. Lift file away from
the steel on each return stroke.
