Maintenance
Service maintenance guide
A. Lubrication
1. A few drops of light No. 10 oil should be placed on the
back edge of each adjusting screw head approximately
after every 4 hours of normal operation.
2. To obtain trouble free trimming, it is necessary to keep the
blades lubricated and clean. The gum that collects and
builds up on the blades can be removed with a 50-50
mixture of kerosene and No. 10 oil. As petroleum products
can shorten the life of some plastics, it is necessary to
remove excess oil-kerosene mixture from the plastic parts.
3. When blades are replaced, or any other time that the
bottom cover plate is removed, the grease level should be
checked for proper amount (approximately 1/2 full in the
area of the gears) and a new gasket should be used to
insure proper seating of the cover plate. Grease should be
added every 25 hours of use. Use EP2 white lithium grease
in the gear housing.
4. Lubricate male spline part of the drive shaft with EP2
White Lithium grease.
B. Storage
1. Store your trimmer in a dry and dust free space, out of the
reach of children.
2. Clean the blades thoroughly and coat them with No. 10 oil
to prevent rust.
3. Perform all required maintenance and service found in this
manual.
4. Use blades cover.
