ELECTRIC CHAIN SAW
SAW CHAIN
TENSION
ADJUSTMENT
WARNING: Unplug chain saw
from power source before adjust-
ing saw chain tension.
WARNING: Cutting edges on
chain are sharp. Use protective
gloves when handling chain.
WARNING: Maintain proper
chain tension 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.
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, page 7). Also make sure adjusting
block is in oval adjusting hole on guide
bar (see Figures 3 and 4, page 7).
2.
Turn adjusting screw clockwise until all
slack is out of chain (see Figure 5).
Note: There should be no gap between
side links of chain and bottom of guide
bar (see Figure 6).
3.
Wearing protective gloves, move chain
around guide bar. Chain should move
freely. If chain does not move freely,
loosen chain by turning adjusting screw
counterclockwise.
4. After chain tension is correct, tighten
guide bar nuts firmly. If not, guide bar
will move and loosen chain tension.
This will increase the risk of kickback.
This can also damage saw. Note: A new
chain will stretch. Check new chain
after first few minutes of operation.
Allow chain to cool down. Readjust
chain tension.

than 1.5 mm
Use a ground fault circuit interrupter as part
of the power supply system.
Use an extension cord heavy enough to
carry the current your saw will draw. An
Guide Bar
undersized cord will cause a voltage drop at
the saw, loss of power, and overheating.
Keep cord away from cutting area. Make
Correct
sure cord does not catch on branches or logs
