Part Three
Maintenance
21
After use, your Cutters Edge Ventilation Saw should be
cleaned and inspected. We
recommend that you develop a
departmental standard operating procedure (SOP) for pe-
riodic inspection, testing and maintenance of your ventila-
tion saw.
Failure to clean the saw after each use can lead to
a less of performance and premature wear or
failure.
CLEANING
To clean the saw, reverse the steps described in the set-
up portion.
CHAIN REPAIR
To have Cutters Edge repair your chain, enclose
a note or purchase order and a street address for
return shipment by UPS and ship your chain to:
Cutters Edge
34385 Broken Oak Lane
Julian, CA 92036 U.S.A
We recommend that you ship your chain to us via
UPS for fastest service. We repair your chain the
day we receive it and return it the next day via
UPS.
We recommend that you keep a minimum of two
chains: one on the saw and one in for repair.
Start by removing the clutch cover. Inspect it and clean all
foreign matter and debris from it (Fig. 26).
Fig. 26. Thoroughly clean the clutch cover.
Remove the outer guide bar plate and wipe it clean.
THE CHAIN
Remove the chain. Inspect it closely.
IMPORTANT
If
the chain has six or more broken cutters, it
should be repaired. If the chain is in satisfactory
condition, clean and lubricate it.
THE BAR
Remove the guide bar and inner bar plate. Wipe all debris
from them.
Clean out the groove using a bar cleaning tool, the edge of
a bar plate, or a putty knife. Also be sure to thoroughly
clean the oil holes on both sides of the bar. If there is
excess buildup on the bar, clean it off with solvent.
Feel along the edges of the bar body. If there are burrs, use
a flat file to lightly file them down.
LUBRICATING THE SPROCKET TIP
After you have cleaned and dried your sprocket tip bar,
lubricate it by squirting grease into the holes in the sprocket
tip, using the grease gun provided with your saw (Fig. 27).
Apply enough grease for a little to ooze out from the
groove. Spin the sprocket to distribute the grease, then flip
the bar and repeat this procedure on the other side.
