• BRAKE FLUID
To check the brake oil level, proceed as follows:
- place the machine on a perfectly even ground
- switch off the Diesel engine
- remove cover "A".
- remove the cap "B" from the control tank
The oil level must be about 3.5 cm from the upper brim of the tank. a slight decrease in the level is due to the normal wear of
brake pads.
This level must never be less than the minimum "MIN"; if necessary, top up to the indicated level without going over the
maximum level ("MAX"). For the type of brake oil to use, refer to paragraph "OIL TABLE" in chapter "STICKERS WITH
CONTROL DESCRIPTIONS - LEAFLETS IN THE CAB".
WARNING!
Significant lowering of fluid level is due to system leakages. Seek the help of skilled personnel to check the system.
Be careful when filling up the appropriate small tank with brake fluid, as it is particularly toxic and could ruin painted
or plastic surfaces.
• SLIDING PADS OF THE TELESCOPIC BOOM (OUTER PADS)
Perform the following checks on all the outer sliding pads of each boom:
1 - visual inspection of outer sliding pads to check for wear
2 - visual inspection of outer sliding pads to check for wear uniformity
3 - visual inspection of the boom surface to check for any indentations due to the
sliding of outer sliding pads
4 - visual inspection of outer sliding pads to check for any burrs or large shavings
(plastic powder is accepted)
Should either condition "1" or "2" occur, please contact Merlo Technical
Assistance Service.
Should either condition "3" or "4" occur, please proceed as follows:
- remove grease from the telescopic boom surface
- adjust the telescopic boom as described in the paragraph "GENERAL MAINTENANCE"
- apply a layer of specific Merlo grease on the telescopic boom, as described in paragraph "OUTER SLIDING PADS OF THE
TELESCOPIC BOOM"
Should the problem persist, please contact Merlo Technical Assistance Service for repair.
NOTE! While extending and retracting the telescopic boom, some paint might be removed from the areas
where the outer pads of the telescopic boom slide. This is to be considered absolutely normal, and it does not
interfere with the correct operation of the telescopic boom.
