Ac Generator Switch; Hydraulic Oil Warm-Up Switch; Pre-Operation Safety Inspection - Snorkel A62JRT Operator's Manual

Horn Switch
The horn switch is to the right of the emergency stop
button on the upper control panel (refer to Figure 4). Hold
the switch upward to sound the horn.
Platform Foot Switch
The upper controls are interlocked through the platform
foot switch.
Step down on and hold the platform foot switch to activate
the drive and boom functions from the upper controls.

AC Generator Switch

The switch for the optional AC generator is located on
the front of the upper control panel.
With the engine running, place the switch in the generator
position to provide electrical power to the electrical outlet
at the platform. Return the switch to the off position to turn
off the generator and resume machine operation.
Machine functions will not operate while the switch is in
the generator position.

Hydraulic Oil Warm-Up Switch

The optional hydraulic fluid warm-up switch is used to
warm the hydraulic fluid when the ambient temperature
is below 0°C (32°F) and boom movement is sluggish
because of cold fluid.
Caution
Not all hydraulic fluid is suitable to use in the hydrau-
lic system. Some have poor lubricating character-
istics and may increase component wear. Only use
hydraulic fluid as recommended.
Use cold weather hydraulic oil as recommended in the
machine General Specifications in temperatures of -12°C
(10°F) or below.
The toggle switches for the warm-up system are on the
lower control panel and on the front of the upper control
panel.
Note
Machine functions are not operational while using the
hydraulic warm-up system.
To warm-up the hydraulic fluid from the upper controls:
1. Start the engine from the upper controls.
2. Place the hydraulic fluid warm-up switch in the on
position.
• The engine throttle speed will increase to warm the
hydraulic fluid.
A62JRT – 104850-000

Pre-Operation Safety Inspection

• The engine throttle speed will decrease and return
to idle once the hydraulic fluid reaches a preset
temperature.
• If the warm-up switch is left on the engine speed
will continue to increase and decrease to keep the
hydraulic fluid at a preset temperature.
3. When the engine throttle speed returns to idle, place
the hydraulic oil warm-up switch in the off position.
Pre-Operation Safety Inspection
Note
Carefully read, understand and follow all safety rules,
operating instructions, labels and National Safety Instruc-
tions/Requirements. Perform the following steps each
day before use.
1. Open the turntable covers and inspect for damage,
fluid leaks or missing parts.
2. Check the level of the hydraulic fluid with the platform
fully lowered. The fluid level must be between the add
and full marks on the sight glass. Add recommended
hydraulic fluid if necessary. See "Specifications" on
page 24.
3. Check the engine oil and coolant levels and make
sure they are at the proper level.
4. Check that all guardrails are in place and all fasteners
are properly tightened.
5. Inspect the machine thoroughly for cracked welds
and structural damage, loose or missing hardware,
hydraulic leaks, damaged control cable and loose
wire connections.
