LOVA Guncrete MACHINE
Dry-Mix Gunite Machine
Operating Principle:
R E E D’s L O VA dry mix gun has
been using the same basic operating
principle for over 40 years.
1. The dry mix is fed through a
hopper into the pockets of the
rotary feed wheel.
2. The rotary feed wheel, driven
by a heavy-duty oil bath gear
drive, rotates the mix under
the conveying air inlet and
material outlet.
3. With the introduction of single source
compressed air, the mix is evacuated
from the feed wheel pockets and then
travels through the outlet.
4. The dry mix is then conveyed in suspension through the dry mix hose to
the shotcrete nozzle where water is
introduced.

OPERATOR QUALIFICATIONS
Making the choice for an operator is a vital decision as it affects safety and productivity. The REED
MODEL CONCRETE LOVA SERIES 4 has been thoroughly inspected and tested by the REED
Quality Control Department prior to shipment. The design of the unit incorporates several built-in
safety features and also allows for an average skilled person to readily become proficient in the safe
operation of the LOVA SERIES 4. The unit is a pressurized material pump and can be potentially
DANGEROUS in the hands of UNTRAINED OR CARELESS OPERATORS.
Knowing the characteristics of the machine and function of the controls are important to SAFE,
PROPER OPERATION and USE.
It is the responsibility of all users to read and comply with the following rules and information
designed to promote SAFETY and UNDERSTANDING of the LOVA SERIES 4 spraying machine.
• The first requirement for any user/operator is to obtain a thorough understanding of the
operating characteristics and limitations of the machine. This should not be overlooked
regardless of their prior experience with similar type equipment.
• Only QUALIFIED TRAINED personnel who have been authorized must be allowed to
operate the REED GUNITE LOVA SERIES 4. A Qualified Trained Operator is one who
has READ and UNDERSTOOD the instructions in this manual and is thoroughly familiar
with the operating characteristics and limitations of the machine.
• Individuals who cannot READ and UNDERSTAND the signs, warnings, notices and
operating instructions that are part of the job, in the language in which it is printed MUST
NOT BE ALLOWED to operate the LOVA SERIES4.
• Know and follow all cautions, warnings and operating instructions on the machine.
• Repair and adjustments must only be made by QUALIFIED TRAINED personnel.
• No modification is to be made to the machine without prior written consent of the REED
Customer Service Department.
• Attach a SIGN-OFF sheet on the unit to enable the operator to report any damage, defects,
problems or accidents to his work supervisor.
• Understand and OBEY all applicab le Local and Government statutes and regulations
applying to safe operation and use of material pumping machines.

PRE-OPERATION INSPECTION
The CONDITION of the unit prior to start-up is a very IMPORTANT factor as it directly affects
the operator’s safety as well as those around him. It should be a common practice that the
operator performs a general inspection of the REED GUNCRETE LOVA SERIES 4 before
each day’s operation.
The purpose of the operator’s inspection is to keep the equipment in PROPER working
condition and to DETECT any sign of malfunction during normal operations between scheduled
maintenance checks.
DOWNTIME is COSTLY and can possibly be prevented by taking a few minutes prior to startup to do a thorough walk-around inspection. This inspection must be performed each day
before the unit is operated. Report any damage or faulty operation immediately. Attach a sign,
if need be, at the control panel which states ------ DO NOT OPERATE ------. Repair any
discrepancies before use.
Some major items to be considered for your inspection include the following:

Defective components, structural damage, missing
parts or equipment malfunctions, jeopardize the
SAFETY of the operator and other personnel and
can cause extensive damage to the machine. A
poorly MAINTAINED machine can become the
greatest OPERATIONAL HAZARD you may encounter.
