Snorkel TB37 2001 - Manual (Page 41)

Drive speed ranges are interlocked through a limit
switch that senses the main boom position. When the
boom is elevated, only the slowest drive speed will work
regardless of the drive range switch position. To avoid a
sudden speed change from high to low elevated boom
speed, always bring the machine to a stop before rais-
ing the booms from the stowed position.
The potential for an accident increases when safety
devices do not function properly. Death or serious
injury can result from such accidents. Do not alter,
disable, or override any safety device.
Do not use the aerial platform if it drives faster than 1.0
miles per hour (44
′
in 30 seconds) when the booms are
elevated from the stowed position.
Four-Wheel Drive
The machine may be equipped with a four-wheel drive
system. This system operates full time and requires no
action by the operator.
Four-wheel drive machines have a “4x4” decal on each
side of the chassis and all four of the wheel hubs are
drive hubs and look the same.
Electrical Power Outlet
The electrical outlet at the platform has 2, 3-prong, 125
volt AC electrical connectors. Their combined output is
limited by a 15 amp circuit breaker.
Power may be supplied to the outlet using an external
power source or by operating the optional AC generator.
To use the outlet, plug a source of power into the
power-input connector on the left side of the lower con-
trol panel. Unplug the source of power before moving
the aerial platform.
AC Generator
The generator can be used to supply power to the elec-
trical outlet only when the engine is running and the ma-
chine is stationary. The machine functions will not
operate when the machine/generator selector switch is
in the generator position.
Cold hydraulic oil does not flow well and may pro-
duce low generator output voltage. Low outlet volt-
age can damage some electrical power tools and
equipment. Warm the hydraulic oil before operating
the generator.
Do not operate the generator unless the hydraulic oil
temperature is at least 100°F (38°C). Refer to Cold
Weather Start-Up for a hydraulic oil warm-up proce-
dure.
Use the following procedure to supply power to the elec-
trical power outlet if the machine is equipped with the
optional generator.
1. Plug the generator cord into the outlet on the left
side of the lower control panel.
2. Start the engine and place the machine/generator
selector switch (refer to Figure 8.3) in the generator
position.
The engine will run at high idle while the generator
is operating. The generator will continue to operate
as long as the engine is running and the switch is in
the generator position.
Dual Fuel
The dual fuel switch is located on the front of the lower
control panel (refer to Figure 8.4).
Figure 8.4—Lower Controls
Before starting the engine, place the fuel switch in the
gasoline or the LPG position. Open the shut-off valve on
the LPG gas tank if using LPG. Always keep the LPG
tank shut-off valve closed when not using LPG.
To switch from gasoline to LPG with the engine running:
1. Open the shut-off valve on the LPG tank.
2. Place the fuel switch in the off position until the en-
gine starts to die.
3. Place the fuel switch in the LPG position.
To switch from LPG to gasoline with the engine running:
1. Place the fuel switch in the gasoline position.
2. Close the shut-off valve on the LPG tank.
Driving Lights
The optional driving lights are for use in dimly lit areas
and are not intended for driving on public roadways.
There are two headlights at the front of the chassis and
two blinking taillights at the rear of the chassis.
The lights are operational when the battery disconnect
switch and the master switch are turned on.
