EM-900SDCE Mixer Maintenance

EM-900SDCE MIXER — MAINTENANCE

SHAFT SEALS

CAUTION

IMPORTANT -DRUM HEAD SEAL CARE

Grease seals every 40 hours of operation using any grade #1 lithium base grease. Apply grease until visible inside of mixing tub (over grease).This will purge seal system of contamination.

The clutch reduction assembly has two separate compartments. Each of which must be filled with its proper lubricant and checked at regular intervals.

The clutch compartment should be filled with a good grade of number 30 SAE engine oil which can be poured through the filler hole located just above the clutch inspection door on the opposite side of the transmission. Fill the clutch compartment with 30 SAE engine oil until it overflows the oil level plug located on the shifter side of the clutch compartment . Check this oil level every two or three months and add oil as required. Drain and refill once a year.

The reduction gear, upper compartment should be filled with number 90 SAE oil, as used in automobile transmissions. The filler plug is at the top of the reduction gear case and the oil level plug is on the same side of the case as the clutch lever. Fill the reduction gear compartment with 90 SAE transmission oil until it overflows the oil level plug. Check this oil level every two or three months and add oil as required. Drain and refill once a year.

PADDLE SHAFT BEARINGS

The paddle shafts in the Multiquip EM900SDCE mixers rotate in sealed ball bearings, which require no additional lubrication as they are packed and sealed at the factory.

There is, on each end of the mixing drum, a zerk grease fitting (pivot point). Grease these fittings once a week as they lubricate the dumping mechanism of the mixing drum.

CAUTION

Failure to lubricate the zerk grease fittings once a week will cause the dumping mechanism to stiffen, making the mixer hard to dump.

ENGINE OIL

1.If engine oil is low, fill engine crankcase with lubricating oil through filler hole (Figure 1), but DO NOT overfill.

2.The oil listed in Table 4 is recommended to ensure better engine performance. Use class CD or higher grade motor oil.

AIR CLEANER (DRYTYPE)

1.Change the air cleaner every 500 hours. See Figure 1 for location of air cleaner.

FUEL FILTER/FUEL TANK

1.Change the fuel filter every 500 hours. Fuel filter is located inside fuel tank.

2.Siphon water out of fuel tank once a year.

CLEANING

ALWAYS make sure engine is OFF before cleaning the inside of the drum. NEVER put hands, fingers or arms inside mixing drum when engine is ON.

NEVER pour or spray water over engine.

For consistent performance, long life and high quality mixing, thoroughly clean the mixer inside and out at the end of each day’s operation.To prevent lumps of dried mortar from forming and contamination of future batches, DO NOT allow a buildup of materials to form on the blades or anywhere inside the drum.
