FITTING THE BAR AND CHAIN (Fig. 3)
- Remove the bar nuts (A) and the chain cover
(B).
- Bring the chain tensioning pin (D) fully towards
the sprocket (E) using the chain tensioning
screw (L).
- Fit the bar (F) on the studs (C).
- Fit the chain (H) inside the sprocket (E) and the
bar groove. Pay attention to the direction of
rotation of the chain (I).
- Position the guard, keeping it tight against the
bar, then tighten the tensioner screw (L) so that
the chain tension pin (D) engages the hole (G)
in the bar. Snug the nuts (A) against the guard,
without tightening fully.
- Tension the chain by means of the tensioning
screw (L).
- Hold the tip of the guide bar up and tighten
the chain cover nuts securely. The chain should
be taut but turn freely by hand.
- The chain is tensioned correctly when it can be
pulled upwards a few millimetres.
WARNING - Check the chain tension
frequently when operating the machine.
Always use protective gloves.
CAUTION: Tension the chain when it is
cold, to prevent it from breaking. Check the
"cold tension" before next use.
CAUTION: A new chain has to be
retensioned more often than one that has
been in use for some time.
CHAIN SHARPENING
The pitch of the chain is of 3/8"x.043".
Sharpen the chain using protective gloves and a
round file of Ø 4 mm (5/32").
Always sharpen the cutters only with outward
strokes observing the values given.
After sharpening, the cutting links must all have
the same width and length.
