Safety Information
Vibrations (Where Applicable)
• Prolonged use of hand held (operated) machines will cause the user to feel the
effects of/from vibrations. These vibrations can lead to white finger (Raynaud’s
phenomenon) or carpal tunnel syndrome. This condition reduces the ability of the
hand to feel and regulate temperature, causing numbness and heat sensations
and may cause nerve damage and circulatory tissue death.
• Not all factors that lead to white finger disease are known, but cold weather,
smoking and other diseases that affect blood vessels and blood circulation as well
as large and long-lasting impact of shocks are considered factors in the formation
of white finger. Note the following to reduce the risk of white finger and carpal
tunnel syndrome;
• Wear gloves and keep your hands warm.
• Take regular breaks.
• All of the above precautions may help reduce the risk of white finger disease but
not rule out the carpal tunnel syndrome. Long-term and regular users are therefore
recommended to observe the condition of your hands and fingers. Seek medical
attention immediately if any of the above symptoms should occur.

Maintenance & Care
Oil Servicing
When changing a machines oil, run the machine for a few minutes. Warm oil will
always drain faster and more through compared to oil that’s cold.
• Place a suitable container below the engine to catch the used oil.
• Remove the oil filler cap/dipstick, oil drain plug and washer.
• Allow the used oil to drain completely
• Reinstall the oil drain plug and new washer, and tighten the oil drain plug
securely. Please dispose of used motor oil in a manner that is compatible with the
environment. We suggest you take used oil in a sealed container to your local
recycling centre or service station for reclamation. Do not throw it in the General
Waste, pour it on the ground, or down a drain.
• 3. With the engine in a level position, fill to the upper limit mark (bottom edge of
the oil fill hole) on the dipstick with the recommended oil.
Use 4-stroke motor oil that meets or exceeds
the requirements for API service classification
SJ, SL, or equivalent. Always check the API
service label on the oil container to be sure it
includes the letters SJ, SL, or equivalent. SAE
15W-40 is recommended for general use.
Other viscosities shown in the chart may be
used when the average temperature in your
area is within the indicated range.

Maintenance & Care
Spark Plug
• Firstly remove the Spark plug cap. This is a push/pull fit.
• Using a suitable spark plug wrench, loosen the spark plug and remove it.
• Inspect the sparkplug. Replace if your inspection finds:
1. Visible Damage
2. Badly fouled with Oil/Carbon
3. Washer health is compromised
• Using a feeler gauge, check the gap of the spark electrode. The gap should be
with these tolerances
0.7-0.8 mm (0.026-0.031 inch).
• Reinstall the sparkplug, firstly winding it by hand, this is to avoid cross threading.
• After properly seated, fully tighten using spark plug wrench.
• When the washer has started to compress tighten to the following instruction:
1. New Sparkplug – a 1/2 Turn tight
2. Re-used Spark Plug – a 1/8 to 1/4 Turn tight
Recommended Spark Plugs – NGK:BPR7ES/Champion:RN7YC
This variation of spark plug is recommended for normal engine running conditions
and temperatures.
Incorrect specifications of sparkplug can cause damage to your machine. Ensure
any sparkplug is correctly gapped and free of any deposits
