Perform scheduled maintenance as outlined in Table 4-1. Secure machine as outlined in paragraph 3-3 before doing maintenance inspections or work. All bolts should be torqued as recommended in Table 4- 2 unless otherwise indicated.

Table 4-1 Maintenance Check List

1.Check hydraulic oil level in tank. Add as neces- sary to bring oil level to bottom of strainer. (See paragraph 4-2 for more details.)

2.Inspect hydraulic lines and fittings for wear or leaks. Replace only with genuine Bush Hog replace- ment parts.

WARNING

WEAR EYE PROTECTION AND USE A PIECE OF CARDBOARD OR WOOD RATHER THAN HANDS TO SEARCH FOR

HYDRAULIC LEAKS. ESCAPING HYDRAULIC OIL UNDER PRESSURE CAN PENETRATE THE SKIN. IF FLUID IS INJECTED INTO THE SKIN IT MUST BE SURGICALLY REMOVED BY A DOCTOR FAMILIAR WITH THIS FORM OF INJURY OR GANGRENE MAY RESULT.

3.Check tractor tire air pressure. It is critical for stability that tractor tires carry proper air pres- sure. Refer to tractor operator’s manual.

4.Check blades and spindle to be sure that no foreign objects such as wire or steel strapping bands are wrapped around them.

5.Check blade bolts for tightness. Tighten to 450 ft./lbs. (609.7 Nm)

6.Clean all debris from machine, especially under- side of deck.

7.Check that cables are tight. Tighten per para- graph 4-7.

8.Inspect blades for wear. Replace if necessary per paragraph 4-6. Always replace both blades with a match pair. Use only genuine Bush Hog replacement parts.

9.Make certain chains and/or side bands are in good repair to minimize potential thrown debris or objects from cutter.

11.Perform BEFORE EACH USE lubrication per paragraph 4-2.

4-2 LUBRICATION (Refer to Fig. 4-1)

BEFORE EACH USE

1.Hydraulic Tank - Check hydraulic oil level. Fill as necessary to bring oil level to bottom of filler strainer or to side fill plug. Filter oil to 10 microns before adding. See paragraph 4-3 for recom- mended hydraulic oils.

2.PTO Driveline Universal Joints - Apply multi- purpose grease, with grease gun.

3.PTO Driveline Guard - Apply 2-3 shots of multi- purpose grease, with a grease gun, to plastic fitting. (1 fitting each end)

EVERY 40 HOURS

1.PTO Driveline - Disconnect PTO driveline, separate the two sections, wipe inner (male) section clean, and apply multi-purpose grease to inside of outer (female) driveline section. Reassemble and install. Pull on each driveline section to make sure yokes lock into place.

2.Slide Assemblies - Wearing gloves, clean sliding surfaces of dirt and grease. Apply thin coat of graphite based lubricant (preferred) or multi- purpose grease.

3.Spindle Assembly - With cutter deck in horizontal position, remove check plug at top of housing and check oil level. Add EP80W-90 gear oil as necessary to fill to check plug.
