OPERATION MANUAL
Maintenance
SAFETY
1. Refer to the Operator’s Manual for your machine. Follow all operating, maintenance, and
safety information in the manual.
2. Place the implement on a firm, level surface. Lower all sections of the implement.
3. Exercise extreme caution when working around or with hydraulic systems. Depressurize
the system when connecting or disconnecting the hose couplings.
4. Wear heavy gloves and a face shield for eye protection when searching for suspected
hydraulic leaks. A high-pressure concentrated stream of hydraulic fluid can pierce the
skin. If such happens, seek immediate medical attention, as infection and toxic reaction
could develop.
5. Do not attempt any adjustments or maintenance to any system of the applicator when the
implement is in motion.
6. Make sure all guards and shields are in place when the applicator is being operated.
7. Never wear ill-fitting, baggy or frayed clothing when working on any drive system
components.
8. Store and transfer gasoline, solvents, cleaners, or any flammable liquids only in Safety
Standard-approved containers.
For Clutched Models
Components
An electric clutch consists of three primary components:
1.
Coil Assembly The clutch’s “power” source contains the coil which generates
magnetic force and requires a 12-volt DC coil.
2.
Rotor Assembly Generally, the input of the clutch includes a keyed hub that mates
with the keyway in the drive shaft. The rotor transmits torque from
the drive shaft to the output or armature assembly.
3.
Armature Assembly The output of the clutch also contains the mechanical brake in a
clutch/brake assembly. The armature transmits torque from the
rotor to the driven load. The sleeve is a secondary component
serving as a spacer between the rotor and field assembly and
also as a support for the field assembly bearing.
