Maintenance And Lubrication - Grillo DUMPER 507 Manuel D'utilisation

CAUTION!
- Disconnect the plug before performing any cleaning, maintenance or repair operation.
Always wear suitable clothing and working gloves.
- When the machine or part of it is lifted to carry out maintenance operations, always
remember to use suitable fixing tools such as holders and safety locks.
- When carrying out maintenance operations and/or when the machine is tilted without
safety locks or supports, never leave it unguarded in places where inexperienced people
and children could have easy access to it.
- Protect the environment: carefully dispose of used oils, petrol and any other pollutant
product!
- Effective maintenance and correct lubrication help to keep the machine fully efficient.
Note: all checks have to be carried out with the machine in horizontal position.
ENGINE OIL
Follow the instructions on lubrication intervals in the relative manual. In general users are advised
to check the oil level every 4 working hours
ENGINE AIR FILTER
Check the filter every 8 working hours. For engines equipped with a dry air filter replace the
cartridge when it is too clogged (do not use compressed air to clean it). For engines equipped with
oil-bath filter, add or replace oil. Use the same oil as for the engine.
TRACK ROLLERS
- Frequently grease the track roller pins (fig. 10)
- Frequently check the track roller tension
The truck capacity is 500 kg, but users are advised to consider the terrain on which the vehicle is
to be used when deciding the load which can be transported. Remember that since this is a
tracked carrier vehicle, it pitches considerably on humps, curbs and steps. When crossing such
obstacles, use low gears and take special care; engage a low gear and retain it until back on level
ground. If the machine is stopped on steep slopes, when releasing the lever (fig. 8, pos. D) the
parking brake is automatically engaged. Although the truck has rubber tracks, remember to take
care in difficult environmental conditions (ice, heavy rain or snow) or on terrains which might make
the vehicle unstable.
RUBBER CRAWLER TRACKS – PRECAUTIONS FOR USE
1) TRACK TENSION
1) When the machine is lifted off the ground, the rubber tracks must sag by 10-15 mm as shown in
the diagram.
2) When the track becomes slack, it must be adjusted via the adjusting screw (fig. 7)
