Handle Lock Figure 2 Before Starting the Engine: • Inspect machine before each use according to the Maintenance Schedule on page 11. • Locate and be familiar with all engine and operating controls (Figure 2). • Inspect cutters carefully before installing.
E-CPU12-I-0113 Starting the Engine/Motor and Controlling the Cut: • • • • - Be sure drum is clear of the ground. Start the engine according to the manufacturer’s instructions. For electric models, depress “On” switch. Engine must be at FULL THROTTLE. Slowly lower the cutter head to the slab surface with the hydraulic drum lift lever. Lift the depth control handwheel knob to unlock and turn to the handwheel until the cutter head reaches the desired depth.
E-CPU12-I-0113 Additional Information: • Since cutter wheels wear, the cutting depth will change. Compensate for wear by adjusting the depth control. To reach greater depth in the concrete it is best to make several passes at increments of 1/8” to 3/16” per pass. Never use a fine spaced cutter head to cut deeper than 1/8”. All deep cuts should be started from a stationary position. When the cutting depth is reached the plane should then move forward.
E-CPU12-I-0113 Remove all rings, watches and jewelry prior to doing maintenance near the hydraulic pump. Maintenance Refer to the engine manual for maintenance information specific to the engine used. Disconnect the machine from the power source. Remove the spark plug lead on the gasoline engine models or disconnect the supply voltage connector on the electric models, before performing any maintenance. All maintenance should be performed regularly by qualified personnel.
E-CPU12-I-0113 Cutter Wheel Inspection: • The steel cutter wheels can be used as long as the teeth can be clearly seen on each cutter wheel and the cutter wheel edge must be clearly above the drum flange edge when pushed towards the drum center. Replace worn out cutter wheels as a complete set. • When changing cutters, check drum assembly for cracks or other damage. Replace bent or worn cutter shafts or cracked drum assemblies. A maximum of 30% wear on shafts before they must be replaced.
E-CPU12-I-0113 Inspect & Tension Belts: • Proper belt tension must be maintained to transmit the engine power to the cutter drum. Slipping belts will over heat, the cutter life will be shortened and the cutting speed limited. Over tensioned belts will shorten the belt and bearing life. 70 ft. lbs. of deflection at the center between the pulley’s, is recommended. !! IMPORTANT!! After tensioning belts make sure engine is level and then tighten all mounting hardware and jam nuts.
