10 / CUTTERS EDGE VENTILATION SAWS
Pull the chain around the bar to be sure the drive links are
properly seated in the drive sprocket.
Now replace the outer bar plate.
Replace the clutch cover, tightening the nuts only finger
tight.
SECURING THE BAR & CHAIN
Wearing gloves or with a shop rag protecting your hand,
pull up on the tip of the bar. While holding up the bar tip,
tighten the chain tension adjustment screw by turning it
clockwise. While still holding up the bar tip, tighten the
clutch cover nuts (Fig. 9). Holding up the tip of the bar takes
out any slack between the bar mounting slot and the two
mounting studs. This will eliminate any upward movement
of the bar when cutting pressure is applied at the bottom of
the bar. Any such upward movement of the bar would
cause the chain to loosen.

WITH A SPROCKET-TIP BAR
If you are installing a sprocket-tip guide bar, adjust the
chain tension so that when you pull the chain down you can
slip a quarter between the bar and the bottom of a cutter or
tie strap at a mid-point along the bottom of the bar (Fig. 10).
The chain should snap back when released.

WITH A HARDNOSE BAR
If you are installing a hardnose guide bar, adjust the chain
tension so that as the chain hangs relaxed you can slip a
quarter between the bar and the bottom of a cutter or tie
strap at a mid-point along the bottom of the bar (Fig. 11).
Do not pull the chain, allow it to hang relaxed.

Slide the chain completely around the bar once or twice to
check that it moves smoothly.
FILLING THE TANKS
WARNING
DO NOT USE GASOHOL OR ALCOHOL-
BLENDED FUELS IN THIS SAW OR ANY OTHER
2-CYCLE ENGINE.
IMPORTANT
Please note that each time you fill up or top off the
fuel tank, always top off the bar and chain oil tank.
The fuel tank and the bar and chain oil tank are
sized so that the saw will always run out of fuel
before it runs out of bar and chain oil, eliminating
the possibility of running the chain dry.
Lay the saw on its side and remove the fuel tank cap. Fill
with a fresh mixture of high octane leaded or unleaded
gasoline and Cutters Edge Synthetic 2-Cycle Oil or a high
quality two-cycle oil. Replace the cap.
NOTE:
Mix Cutters Edge Synthetic 2-Cycle Oil at 100:1
and petroleum-based 2-cycle oils at 50:1 Cutters
Edge 2-Cycle Oil has been developed for use in
all
2-cycle engines' used in the fire service.
