MC-42S CONCRETE MIXER — MAINTENANCE (MIXER)

Lug Nut Torque Requirements

It is extremely important to apply and maintain proper wheel mounting torque on the trailer. Be sure to use only the fas- teners matched to the cone angle of the wheel. Proper pro- cedure for attachment of the wheels is as follows:

1. Start all wheel lug nuts by hand.

2. Torque all lug nuts in sequence. See Figure 30. DO NOT torque the wheel lug nuts all the way down.Tighten each lug nut in 3 separate passes as defined by Table 10.

3. After first road use, retorque all lug nuts in sequence. Check all wheel lug nuts periodically.

NOTE

NEVER! use an pneumatic air gun

 

to tighten wheel lug nuts.

Mixer Storage

For storage of the mixer for over 30 days, the following is recommended:

z Drain the fuel tank completely, or add STA-BIL to the fuel.

z Run the engine until the fuel is completely consumed.

z Completely drain used oil from the engine crankcase and fill with fresh clean oil, then follow the procedures described in the engine manual for engine storage.

z Clean the entire mixer and engine compartment.

z Place the mixing drum in the down position (mouth facing downward).

z Cover the mixer and place it a clean dry area, that is protected from harsh elements.
