EM-70 PLASTER/MORTAR MIXER — MAINTENANCE (MIXER)

Ball Socket and Clamp Face Maintenance

1.If the towing vechicle is equipped with a ball socket, smear socket periodically with multi-purpose grease. This will keep the ball socket well lubricated.

2.Periodically oil pivot points and clamp face surfaces of coupler with SAE 30 WT. motor oil.

3.When parking or storing your mixer. Keep the coupler off the ground so dirt will not build up in the ball socket.

Countershaft Bearing Lubrication

There is 1 set of countershaft bearings (Figure 29) that will require lubrication. Lubricate the grease fitting for each countershaft bearing every 40 hours of operation using any grade lithium base grease.

Figure 29. Grease Fittings (Countershaft)

Wheel Bearings

1.After every 3 months of operation, remove the hub dust cap and inspect the wheel bearings (Figure 30). Once a year, or when required, disassemble the wheel hubs remove the old grease and repack the bearings forcing grease between rollers, cone and cage with a good grade of high speed wheel bearing grease (never use grease heavier than 265 A.S.T.M. penetration (“No. 2.”)

2.Fill the wheel hub (Figure 30) with grease to the inside diameter of the outer races and also fill the hub grease cap. Reassemble the hub and mount the wheel. Then tighten the adjusting nut, at the same time turn the wheel in both directions, until there is a slight bind to be sure all the bearing surfaces are in contact.

Then back-off the adjusting nut 1/6 to 1/4 turn or to the nearest locking hole or sufficiently to allow the wheel to rotate freely within limits of .001" to .010" end play. Lock the nut at this position. Install the cotter pin and dust cap, and tighten all hardware.

Main Gear and Drive Pinion Alignment

1.Disconnect the spark plug wire (gasoline engines). If mixer is equipped with an electric motor remove power cord from AC power receptacle. In addition make sure the clutch engagement lever is dis-engaged to relieve V-belt tension.

2.The countershaft and drive pinion are mounted on a slotted base.To align drive pinion with main gear, loosen the pillow block mounting bolts and move them until the necessary alignment has been made. Remember gears must be paralleled aligned not skewed.

3.Using your hand, slightly move (rock) the drive pulley back and forth to determine the amount of backlash. Insert feeler gauge between gears to determine backlash distance. Backlash should range between 0.007- 0.012 inches (Figure 31).

EM-70S, EM-70P specifications

The Multiquip EM-70P and EM-70S are two robust and versatile electric generators designed to provide reliable power for various applications, ranging from construction sites to special events. Both models are renowned for their performance, durability, and efficiency, catering to the needs of contractors, event organizers, and outdoor enthusiasts alike.

One of the standout features of the EM-70P and EM-70S is their powerful engine. The EM-70P is equipped with a 7,000-watt gasoline engine, while the EM-70S comes with a 7,000-watt propane engine. This dual-fuel capability of the EM-70S not only enhances flexibility but also promotes cleaner and more efficient energy consumption. Both generators feature a heavy-duty steel frame that ensures maximum durability and protection against the rigors of job sites.

Technologically, these generators are designed with advanced noise reduction features. The low-noise operation makes them suitable for use in noise-sensitive environments, such as residential areas and events, allowing users to work or host gatherings without disturbing neighbors. Additionally, the EM-70P and EM-70S are equipped with an easy-to-read control panel, featuring circuit breakers and outlets that include multiple 120V and 240V options, ensuring compatibility with a wide range of tools and equipment.

Another notable characteristic of the EM-70P and EM-70S is their portability. Both models come with sturdy wheels and a foldable handle, making them easy to transport on job sites or during events. Their compact size does not compromise power output, as they can easily handle the demands of multiple tools and devices simultaneously.

Safety is also prioritized in the design of these generators. They feature a low-oil shutdown system which automatically turns off the engine when oil levels are critically low, preventing potential damage. Furthermore, the generators are designed to withstand harsh weather conditions, providing peace of mind to users who require dependable power in any environment.

In summary, the Multiquip EM-70P and EM-70S generators combine powerful performance, noise-reduction technology, user-friendly controls, and safety features. Whether you need a reliable power source for construction, outdoor events, or emergency backup, these generators present an ideal solution that meets diverse power needs efficiently and effectively.
