Saw Chain (Chain) Loop of chain having cutting
teeth for cutting wood. The motor drives chain. The
guide bar supports chain.
Spiked Bumper (Spike) Pointed teeth at front of
saw body beside guide bar. Keep spiked bumper in
contact with wood when felling or bucking. It helps
maintain position of saw while cutting.
Sprocket Toothed wheel that drives chain.
Switch Device that completes or interrupts electrical
circuit to motor of saw.
Switch Linkage This device connects switch to trig-
ger. It moves switch when you squeeze trigger.
Switch Lockout Device that reduces accidental
starting of saw.
Trigger Device that turns saw on and off. Squeezing
trigger turns saw on. Releasing trigger turns saw off.

a living tree.
Undercut An upward cut from underside of log or
limb. This is done while in normal cutting position
and cutting with top of guide bar.
ASSEMBLY
Note: Some models are pre-assembled. Assembly is
not needed on these models.
See Saw Chain Tension Adjustment, pages 16 and 17.
The plastic hardware bag should include:
• two guide bar bolts
• two guide bar nuts
• one Phillips-head tapping screw
1. Lay chain out flat.
2. Install front hand guard onto saw body. Do this by
pressing two mounting stand-outs on hand guard
into hex-shaped holes in saw body (see Figure 3).
3 Insert tapping screw through hand guard and into
saw handle. Tighten screw firmly.
4. Turn adjusting screw counterclockwise (see
Figure 4). Continue to turn adjusting screw until
adjusting block is to rear of adjusting plate.
WARNING: Cutting edges on chain
are sharp. Use protective gloves when
handling chain.
IMPORTANT: Do not clamp chain saw in
vise during assembly.
CAUTION: Do not place chain on saw
backwards. If chain is backwards, saw
will vibrate badly and will not cut.

5. Install guide bar onto saw body. Place rear of
guide bar between adjusting plate and sprocket
support.
IMPORTANT: Make sure to insert adjusting
block into oval adjusting hole on guide bar.
6. Line up holes on sprocket support with center
slot on guide bar and holes in saw body.
7. Insert guide bar bolts through front hand guard, saw
body, center slot of guide bar, and sprocket support.
Attach guide bar nuts to guide bar bolts.
IMPORTANT: Tighten guide bar nuts finger
tight only. Make sure adjusting block is in oval
adjusting hole on guide bar.
8. Place chain around drive sprocket, then along
top groove of guide bar and around guide bar
nose. Note: Make sure cutting edges of chain
are facing the right direction. Position chain so
cutting edges on top of guide bar face guide bar
nose (see Figure 3).
Note: For pre-assembled models, the saw chain
tension is properly set at factory. A new chain will
stretch. Check new chain after first few minutes of
operation. Allow chain to cool down. Follow steps
below to readjust saw chain tension.
1. Before adjusting chain, make sure guide bar nuts
are only finger tight (see Figure 3). Also make sure
adjusting block is in oval adjusting hole on guide
bar (see Figures 3 and 4).
SAW CHAIN TENSION
ADJUSTMENT
WARNING: Unplug chain saw from
power source before adjusting saw chain
tension.
WARNING: Cutting edges on chain
are sharp. Use protective gloves when
handling chain.
WARNING: Maintain proper chain ten-
sion always. A loose chain will increase
the risk of kickback. A loose chain may
jump out of guide bar groove. This may
injure operator and damage chain. A
loose chain will cause chain, guide bar,
and sprocket to wear rapidly.
9. Adjust saw chain tension. Follow steps under Saw
Chain Tension Adjustment, pages 16 and 17.
