Safety Instructions
The Workman GTX Electric is designed and tested to of-
fer safe service when operated and maintained proper-
ly. Although hazard control and accident prevention are
partially dependent upon the design and configuration
of the machine, these factors are also dependent upon
the awareness, concern and proper training of the per-
sonnel involved in the operation, transport, mainte-
nance and storage of the machine. Improper use or
maintenance of the machine can result in injury or
death. To reduce the potential for injury or death, comply
with the following safety instructions.
Read and understand the contents of the Operator’s
Manual before starting and operating the machine. Be-
come familiar with all controls and know how to stop it
quickly. Additional copies of the Operator’s Manual are
available on the internet at www.Toro.com.
This safety symbol means DANGER, WARNING,
or CAUTION, PERSONAL SAFETY INSTRUC-
TION. When you see this symbol, carefully read
the instructions that follow. Failure to obey the
instructions may result in personal injury.
WARNING
To reduce the potential for injury or death, com-
ply with the following safety instructions.
WARNING
The Workman GTX Electric is an off−highway ve-
hicle only. It is not designed, equipped or
manufactured for use on public streets, roads or
highways.
Supervisor’s Responsibilities
1. Make sure operators are thoroughly trained and fa-
miliar with the Operator’s Manual and all labels on the
vehicle.
2. Be sure to establish your own special procedures
and work rules for unusual operating conditions (e.g.
slopes too steep for vehicle operation).
Before Operating
1. Read and understand the contents of the Operator’s
Manual and Operator’s DVD before starting and operat-
ing the vehicle. Become familiar with the controls and
know how to stop the vehicle and engine quickly. Addi-
tional copies of the Operator’s Manual are available on
the internet at www.Toro.com.
2. Keep all shields, safety devices and decals in place.
If a shield, safety device or decal is defective, illegible or
damaged, repair or replace it before operating the ve-
hicle. Also, tighten any loose nuts, bolts or screws to en-
sure vehicle is in safe operating condition.

Workman GTX Electric Page 1 − 3 Safety
While Operating
1. Sit on the operator seat when starting and operating
the vehicle.
2. Before starting the vehicle:
A. Make sure that the AC power supply cord (exten-
sion cord) is disconnected from the vehicle onboard
charger receptacle.
B. Engage the parking brake.
C. Make sure accelerator pedal is not depressed.
D. Check position of direction selector switch and
supervision speed limit switch.
3. Before getting off the operator seat:
A. Stop vehicle, turn key switch to OFF and remove
key from switch.
B. Apply the parking brake.
4. If vehicle is parked on incline, chock or block the
wheels after getting off the vehicle.
Maintenance and Service
1. Before servicing or making adjustments to the ve-
hicle, stop vehicle, turn key switch to OFF, engage park-
ing brake and remove key from the key switch.
2. Make sure machine is in safe operating condition by
keeping all nuts, bolts and screws tight.
3. Do not use open pans of flammable cleaning fluids
for cleaning vehicle parts.
4. Keep battery area free of excessive grease, grass,
leaves and dirt.
5. As the first step in any electrical system repair, open
the battery circuit by disconnecting the conductors be-
tween the battery pack and vehicle components (see
Opening Battery Circuit in the General Information sec-
tion of Chapter 3 − Electrical System). Take care during
repairs, however, to not allow tools or vehicle compo-
nents to complete the battery circuit that was opened.
Connect the conductors between the battery pack and
vehicle components as the last step in the repair.
6. When using metal, uninsulated tools around batter-
ies, do not allow tools to contact both positive and nega-
tive battery terminals simultaneously.
7. Remove jewelry and watches before servicing elec-
trical components of the vehicle.
8. Battery acid is poisonous and can cause burns.
Avoid battery acid contact with skin, eyes and clothing.
Protect your face, eyes and clothing when working with
batteries.
9. Battery gases can explode. Keep cigarettes, sparks
and flames away from the batteries. Always service,
store and charge the vehicle batteries in a well ventilated
area.
10.When connecting the AC power supply cord (exten-
sion cord) to the vehicle onboard battery charger, con-
nect the power supply cord to the vehicle charger
receptacle before plugging the supply cord into an AC
outlet (electrical supply for charger). After charging the
vehicle batteries, unplug the supply cord from the outlet
before disconnecting the supply cord from the vehicle
charger receptacle.
11.If major repairs are ever needed or assistance is de-
sired, contact an Authorized Toro Distributor.
12.To assure optimum performance and continued
safety of the machine, use genuine Toro replacement
parts and accessories. Replacement parts and acces-
sories made by other manufacturers may result in non-
conformance with safety standards and the warranty
may be voided.
13.When raising the machine to change tires or to per-
form other service, use correct blocks, hoists and jacks.
Make sure machine is parked on a solid level surface
such as a concrete floor. Prior to raising the machine, re-
move any attachments that may interfere with the safe
and proper raising of the machine. Always chock or
block wheels that remain on the ground for vehicle sta-
bility. Use jack stands to support the raised machine. If
the machine is not properly supported by jack stands,
the machine may move or fall, which may result in per-
sonal injury (see Jacking Instructions in the Operator’s
Manual and in this Chapter).
14.Make sure to dispose potentially harmful waste (e.g.
batteries, oil) in an environmentally safe manner. Follow
all local codes and regulations when recycling or dispos-
ing of waste.

Torque Specifications
Recommended fastener torque values are listed in the
following tables. For critical applications, as determined
by Toro, either the recommended torque or a torque that
is unique to the application is clearly identified and spe-
cified in this Service Manual.
These Torque Specifications for the installation and
tightening of fasteners shall apply to all fasteners which
do not have a specific requirement identified in this Ser-
vice Manual. The following factors shall be considered
when applying torque: cleanliness of the fastener, use
of a thread sealant (e.g. Loctite), degree of lubrication
on the fastener, presence of a prevailing torque feature
(e.g. Nylock nut), hardness of the surface underneath
the fastener’s head or similar condition which affects the
installation.
As noted in the following tables, torque values should be
reduced by 25% for lubricated fasteners to achieve
the similar stress as a dry fastener. Torque values may
also have to be reduced when the fastener is threaded
into aluminum or brass. The specific torque value
should be determined based on the aluminum or brass
material strength, fastener size, length of thread en-
gagement, etc.
The standard method of verifying torque shall be per-
formed by marking a line on the fastener (head or nut)
and mating part, then back off fastener 1/4 of a turn.
Measure the torque required to tighten the fastener until
the lines match up.

Using a Torque Wrench with an Offset Wrench
Use of anoffset wrench (e.g. crowfoot wrench) will affect
torque wrench calibration due to the effective change of
torque wrench length. When using a torque wrench with
an offset wrench, multiply the listed torque recommen-
dation by the calculated torque conversion factor (Fig.
3) to determine proper tightening torque. Tightening
torque when using a torque wrench with an offset
wrench will be lower than the listed torque recommen-
dation.
Example: The measured effective length of the torque
wrench (distance from the center of the handle to the
center of the square drive) is 18”.
The measured effective length of the torque wrench with
the offset wrench installed (distance from the center of
the handle to the center of the offset wrench) is 19”.
The calculated torque conversion factor for this torque
wrench with this offset wrench would be 18 / 19 = 0.947.
If the listed torque recommendation for a fastener is
from 76 to 94 ft−lb, the proper torque when using this
torque wrench with an offset wrench would be from 72
to 89 ft−lb.
