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
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
NEVER
use muriatic acid to clean the pump. Acid
will dissolve the chrome finish on material cylinder
bore and main hydraulic cylinder rods.
WARNING - ACID CLEANING
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.
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
(Recommended after each Pour)
