DANGER
WARNING
- CAUTION
CONSULTATION

While reading this Manual, the operator must pay particular attention to the symbols shown on the plates.

Do not cover these plates for any reason and immediately replace them if they are damaged.

GENERAL CAUTIONS

This machine is designed as a high performance, high capacity sweeper that can clean in tight and congested areas.

By design this means a narrow wheel base with tight steering capability.

These design requirements can under certain conditions create instability during machine operation.

Instability can be caused by a combination of machine travel speed, abrupt manoeuvring, operation on an incline, low tyre pressure, weight in the hopper and or raised hopper.

For this reason the machine must be driven by a qualified operator who must be properly instructed on how to use it and be aware of the potential risks.

The following are situations known to cause instability in the machine and care should be taken by the operator to assure safe operation:

Lifting the hopper on an incline
- Manoeuvring the machine with the hopper lifted
Abrupt steering
- Manoeuvring with speed, on a slope and/or with weight in the hopper
Low tyre pressure

Inside the cab there is a decal (44, Fig. D) that warns the operator of the risk of instability and provides information on activities to avoid to prevent machine instability.

BEFORE START-UP

1. If necessary, open the right upper door (28, Fig. G) by releasing the fastener (29) with the supplied key, and refuel the machine through the filler neck (10, Fig. F).

CAUTION!

Do not fill the fuel tank to the top, but leave at least 1.6 in (4 cm) from the filler neck to allow the fuel to expand.

Check the dust control system water level through the indicator (8, Fig. G).

If necessary, supply water according to the following procedure:

• Disengage the fastener (10, Fig. G) with the supplied key, then open the left door (9).
• Pour the water in the tanks through the plug (30, Fig. F), or the hose (29).
• Close the plug (30), or roll up the hose (29) and place it back in its housing.

• Close the door (9, Fig. G) and secure it with the fastener (10) by using the supplied key.

• Check that there are no open doors/hoods and that the machine is in normal operating conditions.
