Installing and Adjusting
the Bar and Chain
Never attempt to install,
replace, or adjust the chain
while the engine is running.
WARNING!
1. Using the small end of the plug wrench,
remove the sprocket covernut (turn
counterclockwise to remove) and
remove the sprocket cover.
Installing Tool Attachment
1. Place Multipurpose Engine and the
Splitboom Attachment SBA-P4 on a
clean, flat surface so that both assem-
blies fit end to end. The powerhead
assembly should be facing up, and the
Splitboom Attachment SBA-P4 should
be positioned with the locking hole in
the tube end facing up.
CAUTION!
Keep the open ends of the tubes clean
and free of debris!
. Slip off the protective cover from the
end of the tool, and loosen the coupler
screw knob.
3. Insert the tube into the coupler, with
the tool decal facing up, until the line
of the decal is flush with the end of the
coupler. Twist the tool back and forth
until you are sure it snaps in place by
the coupler latch.
