WARNINGS — CONTINUED
Figure 1-17
To Restore Power
1. The operator must reset the emergency stop button.
• Twist the emergency stop button, and it will pop
out
2. Upon resetting the emergency stop switch, the truck
does not automatically go back to the state it was in
when the button was pushed.
3. The switch panel must have power restored to
continue operation. This will activate the boom and
the hose reel functions at a neutral state.
• The engine RPM must be increased
• Water pump is engaged
• Vacuum relief is closed
Vacuum Operation Safety
• Keep vacuum tools and hoses away from face and
body. An injury caused by vacuum can be serious.
The vacuum must be stopped or the vacuum
pressure relieved as quickly as possible at any sign
of danger. Seek medical attention immediately.
• Do not attach hose, pipe, or accessories with the
vacuum on. The vacuum can trap fingers, hands, and
feet with enough force to crush or cut.
• Do not use a bare open hose end for vacuuming. A
variety of hose and attachments are available to
keep the operator clear of the hose opening.
When operating the vacuum equipment with
extended vacuum hoses or tubes lying horizontal
on the ground, you must install a vacuum relief
T-type valve in the hose line.
NEVER operate the vacuum system without the
vacuum relief valve being installed. Failure to
install and operate the vacuum relief valve
properly may result in serious injury and/or
death.
The in-line vacuum relief valve must be in line
within 50 feet from the end of the hose or pipe for
proper operation.
Make sure no one is near the end of the vacuum
hose and that the vacuum relief door is open
before engaging the vacuum pump. Failure to do
so could cause personal injury.
