PRIOR TO USE
Installing guide bar and saw
A standard saw unit package contains the items as illustrated. (Fig. 1)
(1) Power unit
(2) Bar protector
(3) Guide bar
(4) Chainsaw
(5) Plug wrench
(6) Screwdriver for carburetor adjustment
(7) Spike and mounting screws
Open the box and install the guide bar and the saw chain on the
power unit as follows:
WARNING!
The saw chain has very sharp edges. Use thick protective
gloves for safety.
1. Pull the guard towards the front handle to check that the chain
brake is not on.
2. Loosen the nuts and remove the chain cover.
3. Install the attached spike to the power unit.
4. Gear the chain to the sprocket and, while fitting the saw chain
around the guide bar, mount the guide bar to the power unit.
Adjust the position of chain tensioner nut on the chain cover to the
lower hole of guide bar. (Fig.2).

(9) Tensioner nut
(10) Chain cover
Pay attention to the correct direction of the saw. (Fig.3)
(1) Moving direction
5. Fit the chain cover to the power unit and fasten the nuts to finger
tightness.
6. While holding up the tip of the bar, adjust the chain tension by
turning the tensioner screw until the tie straps just touch the
bottom side of the bar rail. (Fig.4).
7. Tighten the nuts securely with the bar tip held up (12 ~ 15N.m).
Then check the chain for smooth rotation and proper tension while
moving it by hand. If necessary, re-adjust with the chain cover
loose.
8. Tighten the tensioner screw.

(3) Tighten
(4) Tensioner screw
NOTE:
A new chain will expand in length at the beginning of use. Check and
re-adjust the tension frequently as a loose chain can easily de-rail or
cause rapid wear of itself and the guide bar.
Fuel and chain oil
Fuel
• The motor uses two stroke fuel, a mixture of petrol and a 2 stroke
lubricant at 25:1.
• Use a branded 90 octane or higher unleaded petrol.
NOTE two stroke fuel may separate, Shake fuel container
thoroughly before each use. Do not mix more fuel than you
expect to use within one month. (Fig.5).
Recommended mixing ratio:
Condition
Petrol: Oil
Up to 20 hours use
20:1
After 20 hours use
25:1
25:1 Mix chart
Petrol litres 1 2 3 4 5
2-Cycle oil ml. 40 80 120 160 200
WARNING!
• Keep open flames away from the area where fuel is handled
or stored.
• Mix and store fuel only in an approved petrol container.
NOTE:
Most engine troubles are caused, directly or indirectly, by the fuel
used on the machine. Take special care when mixing.
Chain oil
Use motor oil SAE# 10W ~ 30 all year round or SAE #30 ~ #40 in
summer and SAE#20 in winter. (Fig.6).
NOTE:
Do not use wasted or re-generated oil as this will cause damage
to the oil pump.
WARNING
!
2-Stroke engines have a specific horse power and we therefore
recommend the use of branded petrol with a rating of not less
than 90
.
OPERATING INSTRUCTIONS

4. Pull out the choke knob to the closed position. (Fig. 10).
NOTE:
When re-starting immediately after stopping the engine, leave
the choke knob at the open position.
5. While holding the saw unit securely on the ground, pull the starter
rope vigorously. (Fig. 11)
WARNING!
Do not attempt to start the chainsaw whilst holding in one hand
as this can cause injury.
6. When engine has ignited first, push in the choke knob and pull the
starter again to start the engine.
7. Allow the engine to warm up with the throttle lever pulled slightly.
WARNING!
Keep clear of the saw chain as it will start rotating once the
engine has started.
Check oil supply
After starting the engine, run the chain at medium speed and see if
chain oil is scattered off as shown (Fig. 12).
(1) Chain oil
The chain oil flow can be changed by inserting a screwdriver in the
hole on bottom of the clutch side. Adjust according to your work
