PREVENTATIVE MAINTENANCE
How good is any of the equipment you own? It is only as good as it is MAINTAINED. Even the
finest equipment manufactured requires attention and care. The 05 MODEL A30HP is no
different. A good well planned and carried out preventative maintenance program will enhance
a properly operating unit as well as the safety of those operating and using the equipment.
It is very important to establish a good maintenance program. Costly repairs and loss of
revenue can often be avoided by planning ahead, setting a regular schedule and exercising
good preventative maintenance techniques.
The following section is offered as a guide and depicts a start for developing your own
preventative maintenance program for the MODEL A30HP concrete pump. The program is
depicted and broken into sections of INSPECTION and LUBRICATION.
All points noted herein regarding the maintenance
and checks are not intended to replace any local or
regional regulations which may pertain to this type of
equipment. It should also be noted that the list and
schedule is not considered to be inclusive. Interval
times may vary due to the climate and/or conditions
associated with the location area in which the
equipment will be used.
It is your responsibility to always insure that the
applicable safety precautions are strictly observed
when performing the inspections and maintenance
checks. Make certain any components that are found
to be defective are replaced or those in need of
adjustments or repair are corrected before operating
the machine.

LUBRICATION
The MODEL A30HP concrete pump is equipped with several components that because of the
application require frequent lubrication. These areas involve the S-tube shifting mechanism,
swing components, the shift and outlet bearings and agitator. To insure the economical service
and the long life of these components, grease fittings are installed at each point.
Rapid wear and probable component breakdown will
result if the unit is operated with inadequate
lubrication. Follow the recommended interval and if
need be increase the interval when above normal
usage takes place.
LUBE POINT LOCATION
•Swing Tube Shift
•Quantity 1 at cylinder barrel pivot
•Quantity 1 at bell crank
•Quantity 2 at swing tube shaft bearing housing
•Swing Tube Outlet
•Quantity 2 on outlet bearing housing
Recommended Lubricant: GENERAL PURPOSE GREASE, SHELL ALVANIA EPLFH2 or
EQUAL
Recommended Interval: DAILY, BEFORE START-UP AND AS REQUIRED DURING
OPERATION
LUBRICANT AND INTERVAL
The lubricant that is recommended is generally the best choice, however, should this lubricant
be unavailable in your area, consult your local supplier for an equivalent.

On the same basis, recommended lubrication intervals are based on normal use, in normal
environmental conditions. User is CAUTIONED to adjust the lubrication interval accordingly to
meet each individual condition and usage If the swing tube bearing housings become
extremely hot or lubricant becomes a liquid and oozes out around the bearing or seal, the area
should be relubricated.
If the MODEL A30HP has been stored or exposed to environmental conditions of extreme low
humidity, high dust level, elevated temperatures or heavy rainfall, lubrication of components
may be required more frequently than under normal conditions.
External non-bearing surfaces should be wiped
clean of extruded or spilled surplus grease and oil
with a clean, but lint free cloth to prevent damaging
dust and abrasive accumulation on lubricant wet
surfaces.

HYDRAULIC SYSTEM MAINTENANCE
The REED MODEL A30HP utilizes a diesel engine as the main source of power, which drives
the main hydraulic pump. The hydraulic pump is used to supply the flow and develop the
necessary pressure to operate the concrete pump. As with any operational system, it is only as
good as it is maintained. The hydraulic system is a critical system and it is for this reason that
it is IMPORTANT that it receive extra care and good maintenance. This section is offered to
alert you and guide you in maintaining the hydraulic system.
CONTAMINATION is the downfall of most hydraulic
systems and a major contributor leading to system
malfunctions. Extreme care must be exercised to
prevent dirt from entering the system. Make it a
habit to ALWAYS cap or plug open ports and
hydraulic lines.

HYDRAULIC TANK
The hydraulic tank has a capacity of 40 GALS (190L) and is located just forward of the hopper.
It is equipped with a filler breather unit, access cover. A sight gauge is installed on the left side
of the tank and is used to determine the fluid level inside the tank. The tank is also equipped
with drain valve.
Filtration is by a return line filter located on the front of the tank. An oil cooler is adjacent to the
engine cooling unit. This cooler is used to cool the oil prior to entering the tank.
SYSTEM MAINTENANCE ITEMS
The following are specific items for care and maintenance of the hydraulic system.
•FLUID LEVEL Check level daily with sight gauge provided.
Maintain level at full mark. Add through filter.
•TANK BREATHER Clean every 50 hours of operation. Remove from
tank, clean with solvent and air blow dry.
•RETURN LINE FILTER One (1) 10-micron filter; change after first 50
Hours of operation. Thereafter change every
150 hours of operation or when condition
gauge indicates to do so.
•HYDRAULIC TANK Change oil in tank every 1000 hours of operation
or yearly whichever comes first.
After fluid loss for any reason, filter replacement,
component removal etc., sufficient fluid must be
added to properly maintain required level in tank.
HYDRAULIC FLUID
The MODEL A30HP utilizes in its hydraulic system a fluid manufactured by the SHELL OIL
CO. and is designated as TELLUS #46. It is to be used in ambient temperatures of 39 - 90°F
(4 - 32°C). The normal fluid temperature will range from 100 - 167°F (38 - 75°C).
REVISION:

For ambient temperatures of 90°F (32°C) and above use fluid designated as a ISO rating of
68. Use ISO 32 for ambient temperatures of 32°F (4°C) and below.
USE ONLY SHELL TELLUS 46 or equal hydraulic fluid and
NEVER MIX with other type fluids. Always use a CLEAN
fluid. Using impure or other type of fluids not specified will
contaminate the hydraulic system and can lead to eventual
system malfunction or damage and possibly deteriorate the
hydraulic seals.
ADDING HYDRAULIC FLUID
As previously indicated, a hydraulic systems worst enemy is CONTAMINATION. Exercise
extreme care when adding fluid to the hydraulic tank.
•To prevent any dirt or water from entering the hydraulic tank, thoroughly clean area
around top of filter.
•Use fresh clean hydraulic fluid. If a hand pump is used to transfer the fluid, check that
pump filter is clean. If pouring of fluid from a container, pour it through a fine wire mesh
screen, 200 mesh or finer.
Do not use a cloth for straining fluid as lint is harmful to
the hydraulic system.
FILTER SERVICING
The purpose of installing hydraulic filters in the system is to provide a means of continuous
hydraulic fluid filtration in an effort to prevent recirculation of abrasive solids which will cause
rapid wear of component breakdown.
