REPLACING/TENSIONING DRIVE BELT
If the drive belt needs tensioning, the belt should be adjusted so when pressure is
applied in the centre, there is approximately 1/2” slack. See Fig.13.
1) To install a new belt, remove belt guard. Loosen engine mount bolts and slide engine
towards the pump, remove belt.
2) Install proper replacement belt, slide engine away from pump to provide
recommended tension, align pulleys and fasten engine mount bolts.
3) Reinstall belt guard. Belt tension should be checked after 20 hours of operation.
Check belt tension monthly thereafter.
MAINTAINING YOUR ENGINE
Engine Oil Replacement
Oil crankcase capacity: 0.6 litres.
Engine oil should be replaced after the first 20 hours of operation or after the first month
of use, it should be replaced every 100 hours or 6 months after. To replace engine oil:
1) Loosen the oil gauge dipstick (A) Fig.14.
2) Place an oil pan underneath drain hex. bolt (B),
remove hex. bolt (B) and drain oil.
3) Once all the oil has completely drained, retighten the
hex. bolt (B).
Recommended Engine Oil
It is recommended to use SAE 10W30 4-stroke
gasoline engine oil. For cold weather (below -15ºC) use
SAE 5W30.
4) Fill with clean engine oil through the oil gauge dipstick hole, fill then check oil level
until the oil level reaches 3/4 up the dipstick or until it reaches the bottom lip of the
dipstick hole as shown in illustration above.
Inspecting, Replacing or Cleaning Spark Plug (F7TC or equivalent)
The spark plug should be checked every 100 hours of operation or every 6 months. To
replace or clean spark plug:
1) Dismantle the spark plug cap (A) Fig.15 by pulling it off the spark plug (B). Using the
supplied spark plug wrench, undo the spark plug by turning it counterclockwise.
2) Check to see if there is carbon sediment build-up, if so just remove it. If the carbon
sediment is excessive, replace the spark plug.
3) Measure the electrodes clearance. See Fig.16. The spark plug electrode clearance
should be between 0.7-0.8mm. If the clearance exceeds 0.8mm, replace the spark
plug with an LD F7TC or equivalent (NGK BP6ES, Champion N9Y).
4) Reinstall spark plug in the reverse order.
