• The maximum length of electrical extensions should not be over 30m.
If a bigger extension is needed a technician should be quesoned so that
the right gauge will be chosen. A bad dimensioned extension may cause
ire risks and motor burn.
• Engaging the motor at a different voltage results in damage to the
motor;
• Ensure that circuit breakers, electric cables, sockets, and grounding are
compable with that specified in the motor;
• The electrical voltage must not exceed variaons of more or less than
10% as it may cause the motor to burn;
Equipment Cleaning
• The equipment must be unplugged;
• Always clean the equipment aer use;
• Clean the drum with water, removing all residue from the blades,
internal and external parts of the drum;
• Clean the Rack and Pinion, removing all abrasive material from the
components;
• Take care not to wet the motor.

Lubricaon
• Keep machine rotang parts lubricated, such as: pinion, gear ring,
bushings, and bearings (with the help of the grease fings installed in the
machine).
• Lubricate the equipment at the beginning of operaon, applying grease
to all lubricaon points.
• Lubricaon of the pinion/rack gear assembly is not recommended due to
the fact that aggregates such as sand, cement and gravel dust, among
others, can adhere to the lubricang agent, causing the mixture to become
extremely abrasive, thus resulng in premature wear.
Leveling Adjustment and Transportaon
• Do not exceed 5 degrees of inclinaon relave to ground level.
• The equipment has handlebar to raise a few inches from the ground and transport through the wheels;
