6.10.3 LP Gas Pressure Regulator
During the course of normal operation oil or “heavy ends” may build up inside the
secondary chamber of the LPG pressure regulator/vaporiser. The oil and heavy ends
may be a result of poor fuel quality, contamination of the fuel, or regional variation of
the fuel make up. A significant build-up of oil can affect the performance of the pressure
regulator/vaporiser.
The oil should be drained from the LPG pressure regulator/vaporiser periodically in
accordance with the maintenance schedule. More frequent draining of the LPG
pressure regulator/vaporiser is recommended if substandard fuel is used.
Draining Oil Build-up from the LP Gas Pressure Regulator:
1. Park the truck in a well ventilated area
and ensure no external ignition sources
are present.
2. Lower the mast fully and tilt the mast
forward fully.
3. Start the engine and wait until it has
reached its stable operating
temperature. This will help the oil to flow
from the regulator.
4. When the engine is warm, close the
valve on the LPG bottle fully.The engine
will continue to run until it has used up
all the fuel in the fuel lines.
5. When the engine stops, turn the ignition
key switch to the ‘0’ position and remove
the key.
6. Isolate the battery by turning the battery isolator key switch anticlockwise.
7. Open the bonnet (A) from the rear of the truck to gain access to the LPG
pressure regulator (B), which is mounted on top of the engine.
