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

Inspect Tooth Contact between Main Gear and Drive Pinion

1.Coat 3 or 4 teeth at 3 different positions on the main gear with yellow paint.

2.Rotate the drive pulley in both directions.

3.Inspect the tooth pattern.

4.If gear teeth are not contacting properly (Figure 32), adjust pillow block to correct the problem.

Gear Lubrication

The surface of the pinion and main gear (Figure 33) should be very lightly greased.

Figure 33. Pinion and Bull Gear Lubrication

NOTE

Grease main and pinion gears

every 250

hours of

 

 

operation.

IMPORTANT!

 

Avoid over-greasing.

Excess grease will accumulate contaminates and cause premature wear.

Grease Fittings (Zerk) Maintenance (Electric Motor)

1.There are two grease (Figure 34) fittings at each end of the electric motor that will require lubrication. Lubricate these fittings about every 16 months.

2.Use Poleyrex EM (Exxon Mobil) or equalivant lubricant. Clean grease fitting, apply grease gun to fitting (1/2 shot). Remember too much

grease or injecting grease too quickly can cause premature bearing failure. Slowly apply the recommended amount of grease, taking a miniute or so to apply.

Tires/Wheels/Lug Nuts

Tires and wheels are a very important and critical compo- nents of the trailer. When specifying or replacing the trailer wheels it is important the wheels, tires, and axle are prop- erly matched.

WARNING DamagedWheels

DO NOT attempt to repair or modify a wheel. DO NOT install an inter-tube to correct a leak through the rim. If the rim is cracked, the air pressure in the

inter-tube may cause pieces of the rim to explode (break- off) with great force and can cause serious eye or bodily injury.

TiresWear/Inflation

Tire inflation pressure is the most important factor in tire life. Pressure should be checked cold before operation. DO NOT bleed air from tires when they are hot. Check inflation pres- sure weekly during use to insure the maximum tire life and tread wear.

 

WARNING

Eyesight Hazard

 

 

 

ALWAYS wear safety glasses when removing or installing force fitted parts. Failure to comply may result in serious injury.

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.
