FILLING OIL TANK
1. Remove oil cap.
2. Fill oil tank with SAE #30 motor oil. Note: For
temperatures below 30°F, use SAE #10 oil. For
temperatures above 75°F, 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 seep-
age.

Extension Cord Size Requirements
Keep cord away from cutting area. Make sure cord
does not catch on branches or logs during cutting.
Inspect cords often. Replace damaged cords.
This chain saw is designed with an extension cord hitch
that prevents the extension cord from being pulled loose
during use. To use, form a loop with the end of the
extension cord, insert loop into slot in rear of handle,
and place loop over cord hitch (see Figure 4). Gently
pull loop against cord hitch until slack is removed.
Plug extension cord into chain saw cord.
Note: An optional method of retaining the extension
cord is shown in Figure 5. Use this method with
larger-gauge cords that may not fi t into the extension
cord retainer.
EXTENSION CORDS
Use proper extension cords with this saw. Use only
extension cords marked for outdoor use. The cord must
be marked with suffix W or W-A following the cord
type designation. Example: SJTW-A or SJTW.
Use proper sized cord with this saw. Cord must be heavy
enough to carry current needed. An undersized cord will
cause voltage drop at saw. Saw will lose power and over-
heat. Follow cord size requirements listed below.
