ADJUSTING THE SAW CHAIN TENSION
CAUTION:
The guide bar, saw chain, and saw bearings
will wear more rapidly if the saw chain is not properly
tensioned.
Proper saw chain tension is extremely important. Check the saw
chain tension before and during operation. Maintaining proper saw
chain tension will improve cutting performance and prolong the life
of the saw chain.
NOTE: A new saw chain and guide bar will need readjustment after
as few as five (5) cuts. This is normal during the break-in period.
The interval between future adjustments will lengthen quickly.
1. Loosen the bar-retaining nuts so they are hand tight (Fig. 5).
2. Hold the guide bar tip up and use a flat-head screwdriver to turn
the chain-tensioning screw (Fig. 13). Turning the screw clockwise
will tighten the saw chain. Turning the screw counterclockwise
will loosen the saw chain. Depending upon the temperature of
the saw chain, it should be snug to the guide bar (Fig. 14).
3. While wearing heavy-duty work gloves, move the saw chain
back and forth on the guide bar to be sure the chain moves
freely and is in proper mesh with the sprocket. Never move the
chain with your bare hands.
NOTE: If the saw chain binds or does not rotate easily, turn the chain-
tensioning screw counterclockwise, slowly, to loosen the saw
chain. Move the saw chain back and forth until it moves freely.
4. Hold the guide bar tip up and securely tighten the bar-retaining nuts.
SETTING THE CHAIN OIL ADJUSTMENT SCREW
WARNING:
If the chain oil reservoir becomes empty, the
chain oil adjustment screw hole becomes clogged, or the
saw chain fails to receive proper lubrication in any way, the
saw chain will overheat. This can cause irreparable damage
to the unit and serious personal injury.
Lubricating oil will automatically flow from the chain oil reservoir
onto the saw chain during operation. Use the chain oil adjustment
screw to adjust the flow of oil:
1. Insert a 3/32-inch Allen wrench into the chain oil adjustment
screw (Fig. 15).
2. Turn the chain oil adjustment screw counterclockwise to
increase the oil flow.
3. Turn the chain oil adjustment screw clockwise to reduce the oil
flow.
