4. Loop the supplied Terrasaw
drive chain over the large sprocket
(Fig. 3).
5. Engage the drive chain with power
head drive sprocket, ensuring the
drive teeth are seated correctly
(Fig. 4).
Warning: Fitting drive chain with
too much tension will result in
the premature wear and possible
failure of the primary transmission
system.
6. Reassemble the power head side
cover to the power head ensuring
that the chain adjuster is engaged
with the Terrasaw bar and lightly
tighten retaining nuts.
7. Using a screwdriver, adjust the
drive chain so that the slack
is taken up and a light finger
pressure on the drive chain at
midpoint yields approximately half
a chain height deflection. Once the
correct position is obtained, firmly
tighten side cover retaining nuts.
Re-check tension and repeat Step
7 if required.
Note: A new chain will require tensioning more frequently than one that has been
in use for some time. Check the tension of a new chain after only a few minutes
operation and thereafter at each refuelling or as soon as slack is apparent.
Remember: If adjustment is required ensure that the side cover nuts are re-
tightened.
8. Using the aerosol chain wax provided apply a light spray while rotating the
chain by hand, refer also Lubrication page 11. DO NOT START ENGINE AT
THIS TIME.
