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 underneath the engine. Remove oil filler
cap/dipstick and oil drain plug (using a 10 mm
spanner), then let the oil drain into the container
through the opening in the chassis.
Screw the oil outlet drain plug back in and fill the engine with 1.1 Litres of SAE 10W30 or SAE 10W40 through the
oil filler cap/dipstick hole (the oil should reach the thread near the hole opening).
Check the oil level after filling, ensure it is close to, but not greater than the upper limit. 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, first ensure
the belt drive is disengaged by turning the engagement handle anticlockwise. Then, from the fully disengaged position, gently turn
the engagement handle clockwise until you feel it start to resist. From this position, turn the engagement handle clockwise. If the
tension is set correctly, the handle should turn one full revolution clockwise before coming to a stop. If there is a difference greater
than 1/6 of a revolution either clockwise or anticlockwise from one full revolution, then the belt tension should be corrected
following the ‘adjusting belt tension’ procedure.
Adjusting belt tension
Using two 24 mm spanners, unlock the two locking nuts from
above the adjustment block on the engagement handle by
turning the top nut anti clockwise and the bottom nut
clockwise. Then move both locking nuts upward along the
thread.
Rotate the handle clockwise until you start to feel the belt
stretching and beginning to resist. From this position, turn the
engagement handle one full revolution in the clockwise
direction. This is the recommended tension for the belt drive
when in the fully engaged position.
