Manually Lowering The Mast - Generac Power Systems MLT4060M Operating Manual

3. Press and hold the upper winch control switch downward to collapse the mast to its lowest position. Ensure
the electrical cord does not get caught in, or pinched by, the mast while it is being lowered.
Note: Some electric winch models are equipped with an anti-backlash safety limit switch. This switch will disconnect
power to the winch if excess cable slack is detected, preventing accidental lowering of the mast.
STOP IMMEDIATELY if the mast hangs up or the winch cable begins to develop slack.
Excess slack in the cable could cause the mast to collapse, which could result in personal
injury or equipment damage. Contact an authorized service center.
4. Release the mast lock by pulling the safety pin on the mast lock and pulling the lock bar free. Lower the
mast by holding the lower winch control switch to the right until the mast is resting in the transport cradle.
Note: If the mast lock bar does not pull free, activate the lower winch slightly to relieve pressure on the mast bar.
5. After the mast is completely down, insert the mast cradle locking pin and secure it with the safety pin.
Note: If the generator is not operational, and the batteries do not have enough power to lower the mast, it may be
necessary to lower the mast manually.

Manually Lowering the Mast

Do not use this procedure unless it is absolutely necessary. Continuous use of this procedure
could damage the planetary gear brake of the winch. This procedure will not work if the
1. Remove the power cables from the two terminals
on the winch motor assembly (A).
2. Remove the two flange head screws (B) secur-
ing the winch motor assembly to the winch.
Retain the screws for reassembly.
3. Carefully remove the motor assembly (C), mak-
ing sure the two pieces do not separate.
4. Insert a 3/8 in. hex key (D) into the sleeve bear-
ing.
5. Rotate the wrench counter-clockwise to lower
the mast. If any slack is observed in the cable,
stop immediately and remove the slack.
6. When the mast is completely down, reinstall the winch motor assembly, securing it with the screws retained
in step 2.
