CHAIN SAW INFORMATION
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 4). Also
make sure adjusting block is in oval adjusting
hole on guide bar (see Figures 4 and 5).
2.
Turn adjusting screw clockwise. (see Figure
6). Note: There should be no gap between side
links of chain and bottom of guide bar (see
Figure 7).
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. Read just chain tension.
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
tension always. A loose chain will in-
crease 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.
