LS600 PUMP — MAINTENANCE (PUMP)

5.Add water to the hopper. Pump and flush clean the entire hopper, shuttle tube and discharge elbow with water.

6.Scoop out 12 inches of concrete from the inboard end of the delivery hose. “Cork screw” a 6" x 6" x 8" sponge into the end of the first hose section. Reconnect the hose to the discharge elbow.

7.Fill hopper with water. Pump until sponge and clean water come out the discharge end of the hose and line system.

8.When the pump has been used to pump small aggregate concrete (pea rock, ½" minus) or mixes with high fines content (60% or more sand) there will be a tendency for hardened concrete to build up on the inside surface of the shuttle tube. Therefore, at the end of every such pour, after the pump and system have been cleaned and the engine shut off, remove all remaining concrete.

9.When the pump has been used to pump large aggregate concrete (" to 1 (" follow the instructions in step 8 once per week.

Deutz Model BF4L914 Diesel Engine

WARNING - ACID CLEANING

NEVER use muriatic acid to clean the pump. Acid will dissolve the chrome finish on material cylinder bore and main hydraulic cylinder rods.

Use only a 2½" diameter clean-out hook when back-pumping into redi-mix truck. Use a safety chain to secure the clean-out hook to some solid part of the mixer truck to prevent hook from jumping off of the drum. Run the pump at 6 strokes per minute maximum speed.

This pump is equipped with a Deutz BF4L914 turbo diesel engine. For information concerning the procedure in checking, removing, cleaning, etc. of the various engine parts or any other information on the engine not contained herein, refer to the engine manufacturer’s instruction manual.

HYDRAULIC OIL SYSTEM MAINTENANCE

The Mayco pump is equipped with an in-tank return hydraulic filter with a 10 micron cleanable filter.The element has been designed to remove all particles large enough to cause wear and job break down. Under normal conditions, we recommend replacement every 6 month.

The most important factor to keep in mind is the effect of cold weather on the hydraulic oil.The viscosity (thickness) of the hydraulic oil will be much heavier.

ALWAYS run machine until oil temperature reaches a minimum of 50°F. before pumping. Damage to the main piston pump will occur if the machine is cycled too fast before the oil temperature reaches the minimum of 50°F. Cycle the machine at 6-8 strokes per minute at approximately 1/3 throttle.

In areas where the weather normally remains under 50°F., use Shell Oil Tellus 46 (or the equivalent).The above steps must be followed or severe damage to the main axial piston pump can occur.

1.When changing the hydraulic oil or topping off the reservoir, use only the following type. (Reservoir capacity - 50 gal.)

Hydraulic oil: Shell Oil Tellius 68 or

Mobil DFE 26

Texaco Rand HDC

2.Lubrication: Grease daily/Hour

WARNING - HYDRAULIC OIL

DO NOT mix oil brands! This may impair quality.
