If the engine oil needs to be changed, follow these steps:
Run the engine for 1-2 minutes in order to warm up the
oil. Switch the engine off after the oil is warm. Place a
container to the side of the engine. Remove the oil filler
cap/dipstick and oil drain plug (using a 10 mm spanner)
then let the oil drain into the container. Ensure the
machine does not lean more than 30 degrees from
vertical while doing so.
Screw the oil outlet drain plug back in and fill the engine with 0.45 Litres of SAE 10W30 or SAE 10W40 through
the oil filler cap/dipstick hole (the oil should reach the thread near the hole opening).
Using the dipstick, check the oil to make sure it is at the right level (close to the upper limit, but not over). Screw
the oil filler cap/dipstick back into the hole. Dispose of the used engine oil in an environmentally sensitive way.
Belt Tension
Correct belt tension is crucial for minimising belt wear and maximising
machine efficiency. To check the belt tension, the belt guard must first
be removed (see
step 1 of ‘belt replacement’ on pag
e 17). After the belt
guard is removed, fully engage the belt. There should be approximately
5 mm deflection in the belt when pressing firmly on the belt. If required,
adjust belt tension.
Adjusting belt tension
Using two 16 mm spanners, slightly loosen the two
clamping nuts near the bottom of the chipper. Do not
take the nuts completely off the thread.
Using a 13 mm spanner, adjust the bolt at the centre of
the machine frame box section underneath the machine
until the required belt tension is achieved. The belt
should flex by 5 mm when firmly pressing on it.
