VACUUM SYSTEM

VACUUM FAN SCREEN

The vacuum fan screen is located inside the

hopper compartment, Check the vacuum fan

screen for debris daily. Clean with a stiff broom if

required.

The inner top part of the hopper

compartment can be sprayed with water as

well. Do not spray water on the inside walls

of the hopper compartment or anywhere on

the outside of the hopper compartment. If

this is done, water can seep into the

electrical components and damage them.

FOR SAFETY: When servicing machine, wear

eye and ear protection if using pressurized air

or water.

VACUUM HOSES

check the vacuum hoses for blockage and

damage daily.

VACUUM WAND DAMPER

The vacuum wand damper is located behind the

vacuum fan above the debris hopper. The damper

is operated with the vacuum wand damper handle

and controls the vacuum fan air flow between the

main vacuum head and the vacuum wand. If the

surface surrounding the vacuum hose openings is

dirty, the damper will not seal properly.

Check the vacuum damper for proper operation

and debris daily. Wash the around the vacuum fan

damper with a garden hose daily after using the

machine.

FOR SAFETY: When servicing machine, wear

eye and ear protection if using pressurized air

or water.
