Care and Maintenance

Regular maintenance ensures a long effective life for your chain saw.
We recommend you make the following checks on a regular basis:
Oil level
The level in the reservoir should not be allowed to fall below a
quarter full.
Chain and bar
After every few hours of use, remove the guide bar and chain and
clean thoroughly.
(Fig. L2) Ensure the hole between the tensioning/oil hole (18) and the
bar groove is clear.
(Fig. L1) On reassembling, the guide bar should be turned 180˚ and
the sprocket nose oiled via the sprocket lubrication hole (6). This
ensures an even distribution of wear around the guide bar rails.
(Fig. L2) To turn the guide bar through 180˚, remove the small screw
from the slider and re-fasten to the opposite side of the bar.
Saw chain sharpening
To get the best possible performance from your chain saw it is
important to keep the teeth of the chain sharp. Follow these helpful
tips for proper saw chain sharpening:
1.) For best results use a file holder or filing guide to sharpen your
chain. This will ensure you always get the correct sharpening
angles.
2.) Place the file holder flat on the top plate and depth gauge of the
cutter.
3.) (Fig. M1) Keep the correct top plate filing angle line of 30° on
your file guide parallel with your chain (file at 60° from chain
viewed from above).
4.) (Fig. M2) Sharpen cutters on one side of the chain first. File from
the inside of each cutter to the outside. Then turn your saw
around and repeat the processes (2,3,4) for cutters on the other
side of the chain. Use a flat file to file the tops of the rakers

(portion of chain link in front of the cutter) so that they are abo
.025" below the tips of the cutters.
5.) (Fig. M3) Keep all cutter lengths equal.
6.) If damage is present on the chrome surface of the top plates o
side plates, file back until such damage is removed.
CAUTION: After filing, the cutter will be sharp, use extra cauti
during this process
