KICKBACK SAFETY FEATURES
WARNING! The following features are included
on your saw to help reduce the hazard of
kickback; however, such features will not
totally eliminate this danger. As a chainsaw
user, do not rely only on safety devices. You
must follow all safety precautions, instructions,
and maintenance in this manual to help avoid
kickback and other forces which can result in
serious injury.
n REDUCED KICKBACK GUIDE BAR
The reduced-kickback guide bar is designed with a small
radius tip which reduces the size of the kickback danger zone
on the bar tip. A reduced-kickback guide bar has been
demonstrated to significantly reduce the number and
seriousness of kickbacks when tested in accordance with
safety requirements for gasoline powered chainsaws as set
by ANSI B175.1.
n LOW-KICKBACK CHAIN
A low-kickback chain is designed with a contoured depth
gauge and guard link which deflect kickback force and allow
wood to gradually ride into the cutter. Low-kickback chain has
met kickback performance requirements when tested on a
representative sample of chainsaws below 3.8 cubic inch
displacement specified in ANSI B175.1.
If received assembled, repeat all steps to ensure your saw is
properly assembled and all fasteners are secure.
5. Check that the chain brake is in the unlocked position by
pulling the front hand guard towards the front handle.
6. Loosen and remove the bar nuts and the clutch cover
from the saw.
7. Remove the plastic shipping spacer (A) if present.
8. An adjusting pin and screw is used to adjust the tension of
the chain. It is very important when assembling the bar
that the adjusting pin located on the adjusting screw
aligns into a hole in the bar. Turning the screw will move
the adjusting pin up and down the screw. Locate this
adjusting pin before you begin mounting the bar onto the
saw. See following illustration.
n FRONT HAND GUARD
The front hand guard is designed to reduce the chance of
your left hand contacting the chain if your hand slips off the
front handlebar.
The distance and "in-line" position of the hands provided by
the front and rear handles work together to give balance and
resistance in controlling the pivot of the saw back toward the
operator if kickback occurs.
n CHAIN BRAKE
The chain brake is designed to stop the chain in the event of
kickback.
NOTE: We do not represent and you should not assume
that the chain brake will protect you in the event of a
kickback. Do not rely upon any of the devices built into
your saw. You should use the saw properly and carefully
to avoid kickback.
Repairs on a chain brake should be made by an authorized
servicing dealer. Take your unit to the place of purchase if
purchased from a servicing dealer, or to the nearest
authorized master service dealer.
NOTE: If this saw is to be used for commercial logging, a
chain brake is required and shall not be removed or
otherwise disabled to comply with Federal OSHA
Regulations for Commercial Logging.
ASSEMBLY
9. Turn the adjusting screw by hand counterclockwise until
the adjusting pin is positioned between the indicator
marks (B) on the clutch cover. This should allow the
adjusting pin to be near the correct position.
10. Slide guide bar with chain on bar bolts until guide bar
stops against clutch drum sprocket. Cutters must face in
the direction of rotation.
11. Check that the drive links of the chain fit correctly on the
drive sprocket and that the chain is in the groove on the
bar.
12. Fit the clutch cover and insert the adjusting pin in the cut-
out in the bar.
13. Tighten the bar nut finger-tight.
14. Tension the chain by turning the chain tensioning screw
clockwise using the combination tool. The chain is
correctly tensioned when it does not sag from the
underside of the bar, but can still be turned easily by
hand.
