SERVICE INSTRUCTIONS

SAFE MAINTENANCE

Solidly support the under carriage if it

needs to be lifted up for maintenance.

Hydraulic systems may get very hot after

working.

Keep all components in good condition as

they are exposed to high pressures.

Immediately repair damage and replace

worn or broken items.

Keep the tracks clean, removing excess

oil, grease and dirt.

Check for oil leaks and damaged hoses.

Only use recommended lubricants. Do

not mix different brands.

Keep track adjuster grease nipples clean.

TRACK BASE MAINTENANCE (TRACKED MODELS)

To fill with oil, track the chipper until the gearbox casing is level with a

plug positioned at 12 o’clock as shown. Unscrew the two plugs and fill

from the upper hole until oil reaches the level of the lower hole. Replace

both plugs before moving.

NOTE - Ensure the correct grade of oil is used:

Gear Oil EP80W-90 GL5

REPLACEMENT OF OIL IN THE TRACK DRIVE UNIT (TRACKED MODELS)

To drain the oil, track the machine until a plug is at 6 o’clock as shown.

Unscrew both plugs and allow oil to discharge into a suitable container.

Dispose of waste oil in a safe and approved way.

DRAINING THE OIL IN THE TRACK DRIVE UNIT (TRACKED MODELS)

REDUCTION UNIT OIL TYPES (TRACKED MODELS)

We recommend, for track drive gearboxes, using gear oils with E>P. additives and viscosity to SAE

80W/90 or ISO VG 150. Continuous duty temperature must not exceed 90

Maintenance intervals are only guidelines. They should be increased if severe conditions are

encountered. Dispose of lubricants only in accordance with current environmental protection regulations.

VENTING

The TW 190 chippers are subject to vibrations during normal operation. Consequently there is always

a possibility that nuts and bolts will work themselves loose. It is important that periodic checks are

made to ensure the security of all fasteners. Uncalibrated torque wrenches can be inaccurate by

as much as 25%. It is therefore essential that a calibrated torque wrench is used to achieve

the tightening torques listed below.
