Gas Spring

  WARNING 

Disconnect  the  battery  by  separating  the  battery
connector before opening the compartment cover
and  before  inspecting  or  repairing  the  electrical
system. DO NOT place tool on top of the battery. If
a tool causes a short circuit, the high-current flow
from  the  battery  can  cause  personal  injury  or
property damage.

  WARNING 

The capacitor in the traction motor controller can
hold  an  electrical  charge  after  the  battery  is  dis-
connected.  To  prevent  electrical  shock  and  per-
sonal  injury,  discharge  the  capacitor  before  in-
specting  or  repairing  any  component.  Make  cer-
tain  the  battery  has  been  disconnected  and  al-
ways  wear  safety  glasses.  See  Special  Precau-
tions in this section. DO NOT attempt to discharge
the capacitors by shorting the controller.

  WARNING 

The  gas  spring  used  on  the  control  handle  is  in-
stalled  under  tension  and  can  release  with
enough force to cause personal injury or property
damage.

Review the following procedures before removing the gas
spring.

DISCHARGING THE GAS SPRING

  WARNING 

Goggles  and  a  face  shield  must  be  worn  for  per-
sonal protection as metal chips and hydraulic lu-
bricant  may  be  ejected  from  the  drill  operation
due to the high internal pressure.

  CAUTION

The  control  handle  return  spring  is  charged  with
pressurized gas and contains a hydraulic oil lubri-
cant.

NOTE:  

This process is a destructive operation to the gas

spring. A new gas spring must be used during reassembly.
This  is  necessary  because  internal  damage  to  the  spring
components  which  are  not  detectable  could  cause  damage
or injury when the spring is removed.

1. 

Check  that  the  handle  return  spring  is  installed  and
properly  secure  the  control  handle  arm  in  the  full  up-
right  position.  Remove  the  plastic  plugs  to  increase
visibility of the gas spring.

  CAUTION

DO  NOT  damage  the  control  handle  wiring  har-
ness inside the control handle arm.

2. 

Locate and drill a 7 mm (0.25 in.) access hole through
the  center  of  the  control  handle  tube,  approximately
50 mm (2 in.) below the existing access hole.

  WARNING 

Contents  are  under  pressure.  This  process  may
eject metal chips and oil.

3. 

Locate the gas spring inside the control handle through
the  newly  drilled  access  hole  and  drill  a
3 mm (0.125 in.) hole into the gas spring cylinder shell
to relieve pressure.

4. 

Clean up any discharged oil and dispose of in accord-
ance with local regulations.
