GUIDE BAR (52)

CHAIN (57)

1. The Chain (57) tension is proper when the Chain snaps back after being pulled 1/4”
awa y from the Guide Bar (52) with light force . There should be no sagging between
the Chain and Guide Bar underneath. When necessary, use a screwdriver to turn
the Adjustment Screw (61) clockwise to tighten, or counterclockwise to loosen, the
Chain (57). (See Figure D.)

2. NOTE: A Chain (57) which is too taut leads to premature Chain and Guide Bar (52)
wear . A Chain which is too loose may jump out of the Guide Bar groove and dam­age the tool or cause personal injury. New chains typically lose tension initially
during use. When necessary, readjust the Chain tension by follo wing the directions
in Step # 1 of this section.

To Refill The A utomatic Chain Lubrication System:

1. The Chain Saw features an

automatic

Chain Lubrication System with a built-in Oil
Reservoir. Lubrication of the Chain (57) is carried out automatically while the Chain
Saw is running. The oil le vel should be chec ked bef ore each use of the Chain Saw.

2. To refill the Oil Reservoir, unscrew the Oil Fill Cap (11). Fill the Oil Reservoir with a
quality grade chain saw Chain Oil (SAE 30). When filling, avoid introducing dirt or
other foreign material into the Oil Reservoir. Then, retighten the Oil Fill Cap onto the
Oil Reservoir. (See Figure D.)
