Operation

Lifting the System

•

Lift the system with a lift apparatus rated appropri-
ately for the weight of the system (see Technical
Specifications, page 45).

•

Do not lift the system by the handle.

•

Use the lift eyes shown below to lift the system.

Blasting on Higher Surfaces

For example: When blasting 50 ft (15 m) straight up, use
at least 10 ft (3 m) of blast hose on the ground before
the blast hose goes up to the blasting height.

WLD

NOTICE

When blasting on a surface higher than the equipment,
make sure that there is a length of blast hose on the
ground equal to 10-20% of the height. The hose on the
ground prevents unspent abrasive in the hose from
backing up into the internal plumbing of the control box,
which can cause damage to the main air regulator
when the blast switch is disengaged.
