This series of LPG forklift is an advanced model of R series forklift. A set of LPG fuel
system has been adopted，which makes it possible to take both petrol and LPG as fuel.
This service manual is about structure，principle，performance and characteristic of LPG
forklift and its fuel system ，as well as its operation and maintenance, OPERATION AND
MAINTENANCE MANUAL and SERVICE MANUAL of 1-3.5t R series are also concerned. All the
personnel in charge of operation ，maintenance and management should read all these three
manuals completely.
Owing to continuous update and improvement，there
is maybe something different between the explanations
in this manual and the forklift in your hand.

2 Operation
LPG fuel system consists of LPG cylinder, petrol solenoid valve ，LPG solenoid valve with filter, LPG
vaporizer，adapter，LPG-petrol select switch and level indication. passing through the combination valve, the
high-pressured pipe, the filter，and the solenoid valve in sequence，enters the LPG vaporizer to vaporize，
then mix with air in certain proportion in the adapter, and combust in the engine cylinder to drive the forklift
truck to work
1. LPG filling & replacing
Replace the LPG cylinder when fuel in it is used up as following: shut off the outpouring valve，disconnect
the female body from the LPG cylinder，cover a dust cap on the valve tie-in （H2-63）, and get the LPG
cylinder away from the truck to a LPG filling station to refill the LPG. Fill LPG as following: Lay the LPG
cylinder flat, and set the charging limit valve upward(the level indication is exactly 60°to the horizontal
line), then screw off the dust cap on the charging valve，plug the filling connector, open the limit charging
valve to charge LPG till 80% rated volume of the container is full (the charging device is automatically
closed when 80% rated volume of the container is full)，take out the filling connector，screw down the dust
cap and the charging limit valve。Secondly，install the LPG cylinder to the truck by a certain angle (the
level indication is exactly 60°to the horizontal line)，connect the female body，open the outpouring valve，
check and eliminate it if there is any leak before starting the truck. Close the outpouring valve after every
task。
2. Operating the select switch
1．Switch to the GAS position，the fuel for the engine is LPG。
2．Switch to the PET position，the fuel for the engine is petrol。
3．Switch to the neutral position，neither is in use。
3. Starting up the engine
1．By petrol
Shut off LPG，switch on the petrol switch for several seconds，after petrol is flowing into the
floater room of the carburetor，turn the ignition key to start the motor-----the engine is started by petrol。
2．By LPG
a. Starting up when there is no petrol in the carburetor：If there is no petrol in the carburetor before
starting-up，you could start up the engine directly by LPG，that is，to shut off the petrol switch，but switch
on the LPG switch for several seconds，turn the ignition key to start the motor-----the engine is started by
LPG。
b. Starting up when there is petrol in the carburetor：It is some difficult to start up when there is
petrol in the carburetor，you should switch the select switch to the neutral position，start up the
engine by petrol。After petrol in the carburetor is used up and the engine is halted，switch on the
LPG switch，turn the ignition key to start the motor-----the engine is started.
4. Change fuel during the engine runs

8
a. Change from LPG to petrol:
Switch the select switch from GAS position to PET position directly, then the engine use the petrol as
fuel instead of LPG.
b. Change from petrol to LPG
Switch the select switch from the petrol position to the neutral position, when the petrol in the
Carburetor nearly finished, and the engine speed decline, then select the switch to the LPG position swiftly,
and the engine use the LPG as fuel.
5. If there is LPG leak during operation，shut off the LPG switch and the outpouring valve at once，check
every part and all connection to see if there is leak or loose，and get rid of it in time。Fuel by petrol before
malfunction is removed。
6. Choose 90# petrol or LPG special for vehicle as fuel for the truck。Otherwise it may affect the ignition
veracity and decline the motive performance。
7. If there is 10 minutes halt，you should shut off the LPG switch and the outpouring valve.
8. It is suitable to keep water in the radiator in the range 700C~850C during operation.
3. Fuel system parts catalog and maintenance manual
Explanation: The structure of CPQD15~18N-RW21-Y,CPQD20~35N-RW22-Y,CPQD20-35N-RW22A-Y,
CPQD20-35N-RW22B-Y LPG is the same as，CPQD15~18N-RW21（or CPQD15~18N-RW20）,
CPQD20~35N-RW22（or CPQD20~35N-RW11）,CPQD20-35N-RW22A（or CPQD20-35N-RW11A）,
CPQD20-35N-RW22B（or CPQD20-35N-RW11B）except the LPG fuel system.
1. IMPCO Fuel system
There are two kinds of IMPCO changing device
1)、LPG dual-fuel changing device-DFK8634A
2)、LPG single-fuel changing device-K8634A
There are three sections in Impco parts catalog and maintenance manual, they are list, illustration and
dismantle of main pars. For details, please see the reference content.
