Tightening the V-belt / Checking V-belt tension

IMPORTANT:

Exact V-belt tension is essential for maximum cutting 

performance with minimum fuel consumption. Improper 

V-belt tension will result in premature wear to the V-belt and 

V-belt wheel or damage to the clutch bearing.

NOTE:

 The two hex. nut 

(9)

 must be loosened before tightening 

the V-belt or checking the tension.

To increase the belt tension, turn the tension screw 

(10)

 to the 

right (clockwise) with the combination wrench included with the 

Power Cutter.

The belt tension is correctly adjusted when the nut 

(11)

 is located 

as shown in the figure compared to the position of the mark 

(12)

.

IMPORTANT:

After tightening/inspection, make certain to tighten 

• 

the hex. nut 

(9)

 (25 - 31 Nm).

Do not adjust the belt tension while the machine is 

• 

hot. There is a risk of burn injury.

Before operating

1. Checking/replenishing engine oil

With the engine in a cool state, check/replenish engine oil in 

• 

the following way.

Position engine on a flat level, and check to see whether oil is 

• 

within the range of MAX and MIN of the oil tank.

If oil is insufficient (near the MIN mark of the oil tank), fill the 

• 

oil tank with oil to the MAX mark.

Oil quantity can be checked externally without removing the oil 

• 

cap as the oil level can be seen at the external, see-through, 

measuring mark window.

For reference, oil needs to be replenished every ten operating 

• 

hours (one tank of oil for ten fuel refuels).

Replace extremely dirty or discolored oil. 

• 

<Recommended oil> .... Use API grade SF class or higher SAE 

10W-30 oil (automobile 4-stroke engine 

oil).

<Oil quantity> ...............0.22 L (220 mL)

NOTE:

If the engine is not stored in the upright position, oil will 

• 

circulate through the engine, which will mean that there will be 

excessive oil in the Power Cutter when replenishing. 

If oil exceeds the MAX mark, it may leak out causing dirtying 

• 

or white smoke.

Oil replacement Point 1 <Oil cap>

Interval of replacement: Initially, after 20 operating hours, and 

subsequently every 30 operating hours.

Clean away the dirt from around oil filling neck and then 

• 

remove oil cap.

Place the oil cap on a surface where it will not pick up grit and 

• 

dirt. If the cap is put back on in a dirty state, oil circulation may 

deteriorate and engine parts become worn, which may cause 

mechanical failure.

The oil is visible from here, so 

the MAX and MIN marks can 

be used to check the quantity 

of oil.
