3 – CONTROLS AND OPERATIONS
1. The mixing paddles feature adjustable rubber wipers and steel backing plates.
Paddles are factory preset for appropriate drum wrap clearance. If adjustment is
required, proceed as follows:
A. Loosen the wiper attaching hardware and move the wiper outward to
maintain contact with the drum but without folding over when in operation.
B. After adjustment, turn the mixer arms one full turn manually to check
clearance and eliminate the possibility of wiper back plates contacting the
drum.
2. Read through the manual for all operation, adjustment and maintenance
instructions. Be sure all engine/motor and drive system operation instructions
are followed as outlines.
3. All nuts and cap screws should be checked and tightened during the first two (2)
hours of use. Periodic checks should be made thereafter.
