LUBRICATING THE DRIVE GEAR
For best operation and longer lifetime,
lubricate the string trimmer drive gear
with a special grease as described below
after every 50 hours operation. Remove
the sealing screw on the gear case with
the provided Allen key and apply the
grease into the oil hole up to 0.011lb (5g)
(Fig. 28). DO NOT FULLY FILL THE GEAR
CASE WITH THE GREASE.
The grease should meet the following requirements:
◾
NLGI Grade Penetration: NLGI-1
◾
Thickener Type: Ester
◾
Recommended Operating Temperature Range: -40°F to 356°F (-40°C to 180°C)
◾
Other than above, the grease should also have excellent low-temperature startup,
EP, mechanical shearing, abrasion resistance and oxidative stability properties.
TRANSPORTING AND STORING
◾
Clean the tool thoroughly before storing.
◾
Store the tool indoors, in a dry place that is inaccessible to children.
◾
Keep away from corrosive agents such as garden chemicals and deicing salts.
