B3 - CHECK THE HYDRAULIC OIL LEVEL
- Open the distribucing cowling.
- The oil level should reach the middle level of the indictor 1 (Fig. B3), bring the
access platform to the transportation position.
- If necessary, add oil (see chapter “LUBRICANTS”) via the fill orifice A (Fig.
B3).
B4 - CHECK THE SPECIFIC GRAVITY OF THE
BATTERIES ELECTROLYTE
The specific gravity of the electrolyte with temperature, but a minimum of
1270 to 16° C must be maintained.
In the hatched part of figure (Fig. B4), the batteries are charged normally.
Above this area, the batteries need to be re-charged.
The specific gravity must not vary by 0,025 units from one battery cell any other.
- Check the electrolyte specific gravity in each element of the batteries with a
acetometer.
- Never check after filling with distilled water.
- Re-charge the batteries, and wait for 1 hour before checking the specific
gravity.
B5 - CHECK THE BATTERIES ELECTROLYTE LEVEL
Check the level of the electrolyte in each cell of the batteries. Where the
working ambient temperature is high, check the level more frequently than
every 50 hours of operation.
- Open the batteries covers 1 (Fig. B5/1).
- Remove the cap 2 (Fig. B5/2) of each element of the batteries.
- The level should be 1 cm above the top of the plates in the batteries.
- If necessary, top up with clean distilled water, stored in a glass carboy.
- Clean and dry the caps 2 (Fig. B5/2) and replace them.
- Check the battery lugs, and apply Vaseline to them to prevent oxidation.
