Driving And Platform Work Lights - Snorkel 460SJ Operator's Manual

Figure 6.5 – Switch Panel
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. See "Specifications"
on page 5.
The toggle switches for the warm-up system are on the
lower control panel and on the front of the upper control
panel.

• The engine throttle speed will increase to warm
the hydraulic fluid.
• 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.
