GENERAL MAINTENANCE
Oil Sludge Removal from Reservoir
Use plumber's pipe wrench to remove drain cap. Allow free liquid to drain to a pan. Use a spatula to
remove sludge from tank bottom toward drain hole. Use of plumbers tape on the drain pipe threads will
adequately seal the cap to thread contact to prevent leaks.
MONTHLY MAINTENANCE
The following should be performed monthly. Items should be lubricated as directed.
Shaft Bearings
Grease zerk fittings on sealed ball bearing every 20 to 30 hours of use. Rotate shaft periodically while
greasing zerk fittings.
Drive Belts
The belt tension from the motor to blade shaft and worm drive gear are factory preset for immediate
operation. However, the belt tension can be adjusted by adjusting the motor mount plate under the oil
reservoir box with an open end wrench.
Periodically, the belt tension should be checked by removing the belt guard metal cover and ensure
at least 1/2 to 3/4 inch of belt defection is observable. Never over tighten the drive belt as premature
motor, bearing and pulley wear may occur. Even though the
idler pulley contains sealed ball bearings that do not require
lubricant, a small amount of spray oil lubricant or grease
can be used periodically to keep the idler shaft and pulley
in free spinning condition. Do not allow oil or lubricant to
come in contact with the v-belts. Always ensure the spring
on the idler pulley arm is attached and not damaged. Some
periodic lubrication at the idler shaft/pulley will be neces-
sary. Use a light oil for this bearing to shaft contact surface.
