Engine Service and Maintenance
Follow the engine manufacturer’s maintenance
instructions. Should any malfunction occur with
the engine during the warranty period, take it to
an Authorized Service Dealer. DO NOT tear
down the engine, as this may void the Engine
Manufacturer’s Warranty.
NOTE:
Refer to engine manufacturer’s owner’s
manual for all engine service information.
Caring For Vacuum Hoses
1. Inspect hoses before each use. If hoses
have excessive wear, tears, or punctures,
replace immediately.
2. To prolong the life of the hose, periodically
rotate hose and turn hose end to end. Refer
to Preventative Maintenance Schedule in this
manual.
3. Avoid twists and sharp turns in the hoses, as
they will increase wear on the hoses.
4. Avoid dragging the lower hose along the
sides of buildings or other hard surfaces.
Cleaning Exhaust Screen
The exhaust screen on the Z12 is located inside
the container. For best results, clean exhaust
screen regularly.

2. Release the two (2) rubber latches on the
sides of the exhaust cover, and slide screen
out.
3. Clean the screen, and replace.
DO NOT USE THE Z12 WITHOUT EXHAUST
SCREEN SECURELY IN PLACE.
