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 mo-

tor, 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 dam-

aged. Some periodic lubrication at the idler shaft/pulley will

be necessary. Use a light oil for this bearing to shaft contact

surface.
