Maintenance Interval
Before operating the Hedge Trimmer with Hedge Trimmer Attachment it is necessary to check the
adjustment of the cutting blades. Blades that are too loose may vibrate, and will not provide a clean,
smooth cut.
Cutting Blades Maintenance
CAUTION-BLADES THAT ARE TOO TIGHT CAN CAUSE OVERLOADING WHICH MAY DAMAGE
THE EQUIPMENT.
To adjust the cutting blades, refer to the illustrations and locate
the tension screws.
Loosen the tension screw and lock nuts. Gently turn the tension
screws in until sung, then turn the tension screws back out
1/3 -1/2 turn. While holding the screws in place, tighten the
lock nuts. Liberally coat the cutting blades with light oil.
Start the engine and operate the Hedge Trimmer at full speed
for at least one minute. Stop the engine, and when the blades
are motionless, touch the blades with your hand.
The blades may be warm, but if they are too hot to touch,
loosen the tension screws 1/8 turn.

Maintenance Interval
The gearcase and angle drive should be inspect after each 10 to 20
hours of use. Cutting blades should be lubricated at all times.
Lubrication
The gearcase and angle drive should be checked for lubrication
after each 10 to 20 hours of use. Grease fittings are installed into
both components. Use #2 lithium-base bearing lubricant.
Lubrication of the cutting blades should be maintained at all
times. Use a light oil (#10wt.).

maintained properly. Good maintenance includes regular checking of all fasteners for correct tightness,
and cleaning the entire machine. Pitch and gum deposits should be removed from the cutting blades daily.
Adjustment of the cutting blade tension should be checked regularly.
