is not earthed, arrange for an earth to be installed before using the
concrete mixer;
• Should use copper rod length and recommended depth of 2 meters;
• The ground wire to pass through the on / off switch should not be
interrupted or connected to contacts.
• Do not connect the ground wire directly into the mixer neutral wire
mains.
• Grounding must be made according to the standards in the region and
accompanied by a responsible qualified funcon. In the absence of such
standards, should be carried out according to internaonal standards,
doubts when the installaon please contact your authorized service;

Equipment Lubricaon
• Keep machine rotang parts lubricated, such as: pinion, rack gear,
bushings, and bearings;
• 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.
• When lubricang the pimion sha bearing, the concrete mixer drum
must be in a posion where the steel yoke arm is perpendicular (90°) in
relaon to the machine column and the drum mouth must be turned to
the same side where the grease fing is. If not, the bearings will not be
lubricated;
