SAFETY NOTICE: Exposure to vibrations
through prolonged use of gasoline powered
hand tools could cause blood vessel or nerve
damage in the fingers, hands, and joints of
people prone to circulation disorders or
abnormal swellings. Prolonged use in cold
weather has been linked to blood vessel
damage in otherwise healthy people. If
symptoms occur such as numbness, pain,
loss of strength, change in skin color or texture,
or loss of feeling in the fingers, hands, or joints,
discontinue the use of this tool and seek
medical attention. An anti-vibration system
does not guarantee the avoidance of these
problems. Users who operate power tools on
a continual and regular basis must monitor
closely their physical condition and the
condition of this tool.
ASSEMBLY
Protective gloves (not provided) should be
worn during assembly.
ATTACHING THE OPTIONAL
BUMPER SPIKE
The optional bumper spike may be used as a
pivot when making a cut.
1. Loosen and remove the chain brake nuts
and the chain brake from the saw.
2. Attach the bumper spike (optional) with
the two screws as illustrated.
ATTACHING THE BAR & CHAIN (If not
already attached)
WARNING: If received assembled,
repeat all steps to ensure your saw is prop-
erly assembled and all fasteners are secure.
Always wear gloves when handling the
chain. The chain is sharp and can cut you
even when it is not moving!
1. Loosen and remove the chain brake nuts
and the chain brake from the saw.
2. Remove the plastic shipping spacer (if
present).

3. An adjusting pin and screw is used to ad-
just the tension of the chain. It is very im-
portant when assembling the bar, that the
pin located on the adjusting screw aligns
into a hole in the bar. Turning the screw will
move the adjustment pin up and down the
screw. Locate this adjustment before you
begin mounting the bar onto the saw. See
illustration below.

4. Turn the adjusting screw by hand counter-
clockwise until the adjusting pin just
touches the stop. This should allow the pin
to be near the correct position. Further ad-
justment may be necessary as you mount
the bar.
5. Slide guide bar behind clutch drum until
guide bar stops against clutch drum
sprocket.
Mount the bar
6. Prepare the chain by checking the proper
direction. Without following the illustration it
is easy to place the chain on the saw in the
wrong direction. Use the illustration of the
chain to determine the proper direction.
