This manual contains information essential for proper operation and maintenance, as well as
daily lubrication and periodic inspection procedure for your Toyota forklift truck.
Please read this manual thoroughly, even though you may already be familiar with our forklift
trucks, because it contains information which is exclusive to this series of trucks. This manual
is based on a standard truck model. If you have questions about other model(s), please
contact the Toyota forklift dealer (Toyota dealer).
In addition to this manual, please be sure to read the separate publication entitled
"Manual for Safe Operation." It contains important information about the safe operation of
forklift trucks.
Toyota is constantly developing our products. We therefore reserve the right to make
modifications at anytime without prior notice.

2 SAFE USE
2 SAFE USE
Before Starting Operation
▪ Please read this manual thoroughly. This will give you a complete understanding of
Toyota forklift trucks and enable you to operate them correctly and safely. Proper hand 2
ling of a new truck promotes performance and extends service life. Operate with special
caution while becoming familiar with a new truck. In addition to the standard operating
procedures, pay attention to the following safety items.
▪ Please acquire a thorough knowledge of the Toyota forklift truck. Read the oper
ator’s manual thoroughly prior to operating the truck. Get to know its operation and com
ponents. Learn about the safety devices and accessory equipment and their limits and
precautions. Be sure to read the warning labels attached to the truck.
▪ Please familiarize yourself with safe operating points and safe maintenance opera
tion. Understand and maintain work area traffic rules. Ask the work area supervisor about
any special working precautions.
▪ Wear appropriate clothing for operation. Improper clothing for truck operation may in
terfere with smooth operation and cause an accident. Always wear appropriate clothing
for easier operation.
▪ Please keep away from live electric power lines. Know the locations of inside and out
side power lines and maintain sufficient distance.
▪ Be sure to perform preoperation checks and planned maintenance. This will prevent
sudden malfunctions, improve work efficiency, save money and insure a safe working op
eration.
▪ Always warm up the engine before starting operation.
▪ If you hear any unusual noise or sense anything unusual, stop, inspect and repair
immediately.
▪ If the engine stops during traveling, this will affect the operation. Stop the truck in a
safe place and apply the parking brake. Steering operation becomes heavy because the
power steering becomes ineffective. Operate the steering wheel more firmly than usual.
▪ Please use only the recommended types of fuel and lubricants. Lowgrade fuel and
lubricants will shorten service life. Refer to Refueling your truck section of this manual for
the recommended types of fuel.
▪ Flammable and/or combustible materials can be damaged and in some cases ig
nited by a hot exhaust system or hot exhaust gases. To minimize the possibility for
such damage or fire, the operator must obey the following recommended practices:
– Do not operate the forklifts over or near flammable and/or combustible materials, in
cluding dried grass and paper scraps, etc.
– Park the forklift with rear end at least 30 cm (12 in) away from lumber (timber), veneer
board, paper products and other similar materials to avoid discoloration, deformation
or combustion of those materials.

7 OPS FUNCTION
If the operator releases the parking brake within 1 minute after turning off the key switch, a
7 OPS FUNCTION warning sound will also warn the operator.
(Torque converter models) The warning sound will stop after 30 seconds.
(OPS: Operator Presence Sensing) CAUTION
When leaving the seat, always return the control levers to the neutral position, apply

switch and remove the key.
If the operator leaves the seat while the truck is in operation, the OPS indicator lamp will
illuminate and the engine will be stopped.
7.3 Should a problem with OPS occur:
In any of the following cases, a malfunction may have occurred to the OPS. Park the truck in a
safe location, apply the parking brake, remove the key and ask the Toyota dealer for an
inspection.
▪ The OPS lamp does not illuminate when the operator leaves the operator's seat with the
shift lever set in its forward or reverse position.
▪ The OPS indicator lamp does not go off when the operator is in the normal operating posi
tion. (Note: On diesel engine models, indicator lamp may stay illuminated during brief en
gine warmup, if so, this is not an OPS malfunction.)
This truck is equipped with the OPS. Confirm the OPS is functioning properly before operating
truck.
7.1 Travel OPS function
If the operator leaves the seat while the truck is traveling, the OPS indicator lamp will
illuminate and powered travel will be stopped.
However, the OPS is not to be forced to stop its operations. Be sure to be seated during
handling.
The OPS will not apply the brakes to stop coasting or prevent rolling back on inclines.
To restart powered travel, return the shift lever to the neutral position, apply the parking brake,
sit in the seat and start the engine.
The OPS system will not be activated even when the operator leaves the operator's seat if the
shift lever is in the neutral position.
CAUTION
Travel OPS is not a brake. OPS stops powered travel, but does not apply the brake. Ap
ply the parking brake at all times when leaving the operator's seat.
7.2 Parking brake off warning
(Option: European spec./ Australian spec.)
If the operator leaves the truck or turns off the key switch without applying the parking brake, a
warning sound will warn the operator.

correctly. If the spanner indicator lamp does not go off approximately 1 to 2
minutes after engine starts or when the engine speed is increased, stop operation
and have the truck inspected by the Toyota dealer. (Torque converter models) (For
diesel engine models, the spanner indicator lamp may stay illuminated during en
