OPERATING INSTRUCTIONS
OPERATING PRECAUTIONS
1. Keep bystanders 50 feet (15 meters) away when operating the saw.
2. Do not use the pole saw to cut down trees. Use a chain saw without a pole attachment.
3. Make sure the oil tank is full and oil is lubricating the chain prior to starting.
4. Grip pole saw/ trimmer securely—one hand on the grip, the other on the handle.
5. Keep finger off the trigger until ready to make cut.
6. Before starting the pole saw, make sure the chain is not
touching anything.
7. Keep all parts of your body away from the chain when the
saw is running.
8. Do not force the chain saw while cutting. Apply light
pressure. It will do the job better and safer at the rate for
which it was intended.
9. When cutting limbs or branches that are under tension,
use extreme caution. Be alert for wood springing back.
When wood tension is released, the limb could spring
back and strike operator causing severe injury or death.
10. When carrying pole saw from one place to another:
• hold pole at balance point
• keep guide bar and chain to the rear
11. Do not cut small brush and saplings with the pole saw.
Slender matter may catch in the chain and be whipped
toward you. This could also pull you off balance.
12. Never stand directly under the limb you are trimming. Always
position yourself out of the path of falling debris (Fig. 4).
13. Never stand on a ladder or other type of unstable support
while using the pole saw.
14. Always use both hands to operate pole saw. Keep a firm,
steady pressure on the pole saw while cutting, but do not
try to force the saw through the wood.
15. Keep other persons away from cutting end of pole saw
and at a safe distance from work area. (Fig. 5).
16. Do not use the pole saw near cable, electric power or
telephone lines. Maintain a minimum clearance of 50 feet
(15 m) from all power lines (Fig. 6).
STARTING INSTRUCTIONS
Start and operate your pole saw without assistance. For specific starting instructions, see the
appropriate section of your powerhead manual. Proper starting methods reduce the risk of injury.
1.
Place the pole saw on firm ground or other solid surface in an open area.
2. Maintain good balance and secure footing.

WARNING: Oil constantly flows from the oil reservoir to oil the chain. Check the oil
level constantly so that the oil level does not drop below half full.

WARNING: To reduce the risk of fire and burn injuries, start the engine at least 30 ft.
(9.1 m) from the fueling spot, outdoors only.
ASSEMBLY INSTRUCTIONS
CAUTION: Add-ons are to be used in the primary hole only. Using the wrong hole
could lead to personal injury or damage to the unit.
WARNING: Kickback may occur when the nose or tip of the guide bar touches an
object, or when the wood closes in and pinches the saw chain in the cut. Tip contact in
some cases may cause a lightning-fast reverse action, kicking the guide bar rapidly back
towards the operator. Pinching the saw chain along the top of the guide bar may push
the guide bar rapidly back towards the operator. Either of these reactions may cause you
to lose control of the saw, which could result in serious injury to the user.
Do not rely exclusively upon the safety devices built into your saw. As a chain saw user,
you should take several steps to keep your cutting jobs free from accident or injury.
WARNING: Do not use the pole saw to cut
limbs larger than 4” (10 cm) in diameter.
