with the bar and chain are in the immediate vicinity.
2. Hold the front handle rmly with the left hand and put
your right foot onto the base of the rear handle.

STARTING A COLD ENGINE

See gure 3. See gure 8 - 14.
1. Make sure the chain brake is in the run position (A) by
pulling back on the lever/hand guard.
2. Set the ignition switch to the run (I) position (16).
3. Fully press and release the primer bulb (4) 10 times.
4. Pull choker lever (5) all the way out to full position (E).
The partial throttle position is automatically set when
the choke lever is set at full choke.
5. Pull starter (7) until engine attempts to start. Slowly
pull the starter grip out for a short distance until you
feel the starter engage, then briskly pull straight up. Do
not pull to the end of the rope; this may damage the
starter. Hold onto the grip during rewinding. Pull the
starter rope until the rst ring of the engine is heard
(no more than ve pulls).
NOTE: A new unit may require additional pulls.
6. Push choke lever (5) all the way in (G).
7. Pull starter until engine runs.
NOTE: Allow the saw to run in this position 15-30
seconds depending upon the temperature.
8. Squeeze and release the throttle trigger (14). Depress
the throttle trigger which releases the trigger lock
button. Squeeze and release the throttle trigger to let
the engine idle.
CAUTION
Failure to release partial throttle when chain brake lever
is in the brake position will result in serious damage to
the unit. Never squeeze and hold the throttle trigger
while the chain brake is in the brake position.
Now you are ready to pick up the saw. Use the proper
grip for both handles. Refer to "Operation-proper grip on
handles" later in this manual for additional information.

STARTING A WARM ENGINE

Follow the instructions for starting a cold engine (steps
1-9), but do not attempt to start in the full choke position
(skip step 6). Push and release primer bulb 10 times. Pull
the choke out and push it back to the original run position.

STOPPING THE ENGINE

See gure 15.
Release the throttle trigger and let the engine return to
idle. To stop the engine, move the ignition switch to the "O"
stop position (16). Do not put the chainsaw on the ground
when the chain is still moving. For additional safety, set the
English (Original instructions)
chain brake when the saw is not in use.
In the event that the ignition switch will not stop the saw,
pull the choke lever out to the fully extended position (Full
Choke) and engage chain brake to stop the engine. If the
ignition switch will not stop the saw when set to the "O"
stop position, have the ignition switch repaired before
using the chainsaw again to prevent unsafe conditions or
serious injury.
IMPORTANT: When you have nished using the saw,
relieve tank pressures by loosening the chain lubricant
and fuel mix caps. Then retighten the caps. Cover the
sharp chain and bar with the appropriate scabbard. Allow
the engine to cool before storing.

PREPARING FOR CUTTING

Refer to "Speci c Safety Rules – proper clothing for safety"
earlier in this manual for appropriate safety equipment.
Proper clothing for safety
See gure 16.
Proper grip on handles
See gure 17.
Never use a left-handed (cross-handed) grip or any
stance that would place your body or arm across the
chain line.
26 26
Wear non-slip gloves for maximum grip and protection.
Wear loose-fitting clothing (A). Always wear heavy,
long trousers (B), boots (C), and gloves (D). Do not
wear jewellery, shorts, sandals, or go barefoot. Do not
wear loose fitting clothing, which could be drawn into
the engine or catch the chain or undergrowth. Wear
overalls, jeans, or leggings made of cut-resistant
material or ones that contain cut-resistant inserts.
Secure hair so that it is above shoulder level.
Wear non-slip safety footwear and heavy-duty gloves
to improve your grip and to protect your hands.
Wear eye (E), hearing (F), and head (G) protection
when operating this equipment.
Hold the saw firmly with both hands. Always keep your
left hand on the front handle and your right hand on
the rear handle so that your body is to the left of the
chain line.
WARNING
Maintain a proper grip on the saw whenever the engine
is running. The fingers should encircle the handle and
the thumb be wrapped under the handlebar. This grip
is least likely to be broken (by a kick-back or other
sudden reaction of the saw). Any grip in which the
thumb and fingers are on the same side of the handle
is dangerous because a slight kick of the saw can
