SAW CHAIN TENSION
ADJUSTMENT
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 6). Also make sure adjust-
ing block is in oval adjusting hole on guide bar (see Figure
3 and 4, page 6).
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.

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.
FILLING OIL TANK
1. Remove oil cap.
2. Fill oil tank with SAE #30 motor oil.
Note:
For tempera-
tures below -1°C, use SAE #10 oil. For temperatures above
24°C, use SAE #40 oil.
3. Replace oil cap at once. Tighten oil cap firmly for good
seal. This will avoid oil seepage from tank.
4. Wipe off excess oil.
Note:
It is normal for oil to seep when saw is not in use.
Empty oil tank after each use to prevent seepage.
