McCulloch MAC 250 B instruction manual Maintenance, Check for Loose Fasteners and Parts

S WHEN BLADE THRUST OCCURS --Blade Thrust can occur without warning if

the blade snags, stalls, or binds. This is more likely to occur in areas where it is difficult to see the material being cut. By using the unit properly, the occurrence of blade thrust will be reduced and the operator will be less likely to lose control.

SCut only grass, weeds, and woody brush up to 1 cm in diameter with the weed blade. Do not let the blade contact material it cannot cut such as stumps, rocks, fences, metal, etc., or

clusters of hard, woody brush having a diameter greater than 1 cm.

SKeep the blade sharp. A dull blade is more likely to snag and thrust.

SCut only at full throttle. The blade will have

maximum cutting power and is less likely to bind or stall.

S“Feed” the blade deliberately and not too rapidly. The blade can thrust away if it is fed too rapidly.

SCut only from your left to your right. Cutting on right side of the shield will throw debris away

from the operator.

SUse the shoulder harness and keep a firm grip on the unit with both hands. A properly adjusted shoulder harness will support the weight of the unit, freeing your arms and

hands to control and guide the cutting motion. S Keep feet comfortably spread apart and braced for a possible sudden, rapid thrust of unit. Do not overreach. Keep firm footing and

balance.

S Keep blade below waist level; it will be easier to maintain control of unit.

SDo not raise the engine above your waist as the blade can come dangerously close to

your body.

SDo not swing unit with such force that you are in danger of losing your balance.

Bring the engine to cutting speed before enter- ing the material to be cut. If the blade does not turn when you squeeze the throttle trigger, make sure shaft is fully inserted into the engine.

Always release the throttle trigger and allow engine to return to idle speed when not cut- ting. The blade should not turn while the en- gine is running at idle. If the blade turns at idle, do not use your unit. Refer to the CARBURE- TOR ADJUSTMENT section or contact your authorised service dealer.

SMaintain good firm footing while using the unit. Do this by planting feet firmly in a comfortable apart position.

SCut while swinging the upper part of your body from left to right.

SAs you move forward to the next area to cut, be sure to maintain your balance and footing.

RECOMMENDED CUTTING POSITION

WARNING: The operator or others must not try to clear away cut material with the engine running or the blade turning to avoid serious injury. Stop engine and blade before removing materials wrapped around blade or shaft.
