MAINTENANCE

It is recommended that:

At

15,000 mile (24,000 km) intervals or every 18 months, whichever is the sooner, the hydraulic brake and

clutch fluid should be completely renewed.

At

37,500 mile (60,000 km) intervals or every 3 years, which ever is the sooner, all hydraulic brake and fluid,

seals and flexible hoses should be renewed, all working surfaces of the master cylinder, wheel cylinders and

caliper cylinders should be examined and renewed where necessary.

At

37,500 mile (60,000 km) intervals remove all suspension dampers, test for correct operation, refit or renew

as necessary.

At

two

year intervals or at the onset of the second winter, the cooling system should be drained, flushed and

refilled with the required water and anti-freeze solution.

The battery electrolyte level should be checked and topped up if required

once a year in tropical and sub-tropical climates

once every three years in temperate climates.

NOTE: Climatic and operating conditions affect maintenance intervals to

a

large extent: in many cases,

therefore, the determination of such intervals must be left to the good judgement of the owner or to
advice from an Authorised Dealer but the recommendations

will serve as a firm basis for maintenance

work.

Vehicles operating under arduous conditions will require more frequent servicing, therefore, at a minimum, the
Maintenance intervals should be reduced by half.

For low mileage vehicles it is recommended that the maintenance is carried out at

6

months intervals.

The owner need not perform recommended maintenance

in

order

to

maintain the emission warranty or

manufacturer recall liability.

SPECIAL OPERATING CONDITIONS

When the vehicle is operated in extremely arduous conditions

or

on dusty, wet or muddy terrain, more frequent

attention should

be

paid to all servicing requirements.

ADDITIONAL DAILY O R WEEKLY ATTENTION DEPENDING ON OPERATING CONDITIONS:

Check/top-up transfer box

oil.

Check steering rubber boots for security and condition. Renew

if

damaged.

Check brake fluid level: consult your Dealer if any fluid loss

is

suspected.

Clean brake discs and calipers.

Lubricate front and rear propeller shaft grease points and front sliding joint. Under tropical or severe conditions,
particularly where sand

is

encountered, the sliding joints must

be

lubricated very frequently

to

prevent ingress

of abrasive material.

Every week and every maintenance inspection check tyre pressures and inspect tyre treads and side walls.
Under arduous cross-country conditions the tyre pressures should

be

checked much more frequently, even to

the extent of a daily check.

MONTHLY

Renew gearbox oil.
Renew transfer box oil.
Check air cleaner element and renew every 6 months or as necessary.
