ASSEMBLING THE GUIDE BAR AND SAW
CHAIN (FIG. B)
Wear gloves Make sure the bar pad, drive
sprocket, and tensioning pin are free of debris
• Adjust the tensioning screw as far back toward
the rear of the cutting head as it will go
• Place the guide bar on the bar pad by sliding the
bar slot over the alignment flange (1), making
sure the tensioning pin is inserted in the bottom
hole in the tail of the bar
• Loop the saw chain onto the drive sprocket so
that the cutting edges of the teeth along the top
of the bar face away from the cutting head (2)
• Feed the chain into the groove of the bar and
slide the bar away from the motor to remove
slack from the chain (3) Adjust the position of
the tensioning pin until it engages the hole in
the bar
• Install the side cover, making sure the chain
catch is properly seated in its hole, then lightly
tighten the side cover knob (4)
IMPORTANT: The saw chain must be properly
tensioned before using See "Tensioning the Saw
Chain"
TENSIONING THE SAW CHAIN (FIG. C)
Wear gloves
• Remove the battery before tensioning
• Loosen the side cover knob
• Hold up the nose of the guide bar (1), and tighten
the tensioning screw
• Tighten the tensioning screw until the lowest
cutters underneath the bar solidly contact the
bar (2)
• Tighten the side cover knob
• Saw chain tension is correct when, with some
effort, a gloved hand can pull the chain smoothly
around the bar The chain should touch the
underside of the bar rail (3)
After a short period of use, allow the chain to cool
and once again check the tension (remove the
battery first) Watch tension carefully for the first
half-hour of use and periodically throughout the
life of the chain, readjusting as required when the
chain and bar are cool to the touch Never tighten
chain when it is hot
