General Safety Instructions
to make the machine and the operation of same as safe as possible. Shielding, simple adjustments
and other safety features were built into the paver wherever possible.
All machinery should be operated and serviced only by responsible
persons who have been properly instructed and delegated to do so. Read
and thoroughly understand all instructions contained in this manual, the
engine manual, and all optional equipment manuals before attempting to
operate or service the paver.
1) Only the operators should be allowed on the operator's platform when the paver
is in operation.
2) Clothing worn by all persons working close to the paver should be fairly tight and
belted. Loose jackets, shirts or pants should never be worn because of the
danger of getting caught in moving parts.
3) Be sure all shields and guards are in place and in good condition before starting
the machine.
4) Always mount and dismount the paver from the rear, using the walkway, steps and
handrails provided. Never dismount the paver to the side or forward.
5) Assure that all hands and feet are clear of moving parts before starting the paver.
6) Make sure everyone is clear of the paver before starting so they cannot be struck
by or caught in moving parts.
7)
arms, the machine could possibly overturn.
8) Keep the operator's platform clean, Do not use it as a place to carry loose tools,
lunch boxes, etc.
9) Refuel the paver only when the engine has been shut off. Do not permit sparks,
the paver with screed burners lit and operating.
10) Never allow horseplay near the paver when it is in operation or being serviced.
Safety is no accident - Take time to be safe!!!!
One of the primary considerations in designing and manufacturing this PavMaster by GILCREST was
open flames or smoking within 50 feet of the paver when refueling. Never refuel
Never attempt to tow or move the PavMaster before first engaging the tow hitch

Escaping hydraulic fluid under pressure can have sufficient force to
penetrate the skin, causing serious personal injury. Before disconnecting
any hydraulic lines, be sure to relieve all pressure. Before applying
pressure to a system , be sure all connections are tight and that all lines,
tubes, and hoses are not damaged. Fluid escaping from a very small hole
can be almost invisible. Use a piece of cardboard or wood, rather than
hands, to search for suspected leaks.
11) If injured by escaping fluid, see a doctor at once. Serious infection or reaction can develop
if proper medical treatment is not administered immediately.
12) Always be sure that all control switches are in the "OFF", “Pause”, or “Neutral” position,
hopper wings and screed are lowered and the engine is shut off before leaving the
operator's station.
13) Never use the wash down system when the screed burners are lit or operating.
14) Never clean, lubricate, or service the paver when it is running.
15) Do not open propane valves to the screed burners unless flame is present to light the
burners. An accumulation of unburned gas could result in explosion. Do not allow
smoking when lighting propane fired screed burners.
16) Do not allow smoking or the use of open flame when checking the electrolyte level in the
battery. An explosion could result. If skin or eyes are exposed flush immediately with
water and see a doctor.
Safety suggestions for persons working in the area of an operating paver
1) When working in the vicinity of the machine, stand in full view of the operator; but never
in front of the machine when the machine is operating. Stay clear of hopper, side arms,
and screed when machine is operating. Do not walk in front of the hopper or extended
screed, or stand at the end of the screed if the hydraulic screed extensions are being
used.
2) If necessary to remove spillage from the roadway, have the operator stop the machine
first. Working close to a moving machine is dangerous.
Accidents don't just happen- they are caused!
Take time to be safe!!!

3) Do not remove paving material from the hopper or auger trough while the paver is
operating. The operator should be advised when adjustments are being made.
4) Do not attempt service or repairs you do not understand or cannot perform competently.
5) Never go between the tuck and the paver.
6) Do not attempt to clean, lubricate or service the paver while it is running.
7) If any safety related defects are discovered, inform the operator to shut the machine
down and correct the defect.
Pick up and transportation procedure
procedure for your truck. The proper chain link to maintain a level and stable condition
should be located and marked permanently with paint or wire. If the truck used to transport
the PavMaster is a short bed vehicle, a small winch should be mounted to the frame of the
truck to secure the bed in the horizontal position.
A trailer is recommended for this function. The transportation of the PavMaster for short

Assembly Units
POWER UNIT GROUP
The Power unit group consists of a heavy-duty 20-horse power engine that is coupled to a
triple gear pump. The pump nearest to the engine is an eight GPM(gallon per minute) pump, and
drives all hydraulic cylinder functions (gates, wings, screed extensions, screed lift and tow hitch arms).
The next two pumps drive the left and right augers. These are four GPM pumps each.
If your paver has the electric over hydraulic backup option, this is a four GPM pump driven by
an electric DC motor. This pump will drive all cylinder functions. This pump cannot drive the auger
drive functions. This backup system may be used by actuating the ignition key switch counter-
clockwise, to the electric hydraulic position on the ignition switch.
These pumps are capable of driving all cylinder functions of the machine. The appropriate valve must
be actuated, for the function you are attempting during the stroking motion of the pump.
HOPPER ASSEMBLY
side. The wings are hydraulically operated, which allows the operator to raise and lower them with
ease. The lowering of the wings eliminates any truck/paver interference and also allows easy access
lowering of the wings eliminates any truck/paver interference and also
to the asphalt mix from the side of the paver. This is especially valuable when you need to shovel from
the hopper.
WARNING: Never attempt to remove asphalt mix from an operating
machine. Instruct the truck driver and the paver operator to cease
operation before attempting to remove mix from the hopper.
The hopper gates are hydraulically operated with adequate pressure to close the gates, when
the hopper is full of asphalt. There is a PO check on the gate cylinders that will not allow the gates to
“creep” open when loaded. The gates may be operated independently or as one by adjusting the
valves located on the hopper back, directly above the hydraulic pump cover. The double acting
cylinders on the gates permits trouble free metering of material on the open and close operations, and
will eliminate excess material clean up at the end of the paved mat.
All JMG Equipment Company tow type asphalt pavers are equipped with manual hand pumps.
The hopper on the PavMaster by Gilcrest tow type pavers is eight feet wide with a wing on each

SCREED ASSEMBLY
standard paving width of eight feet, and can be hydraulically extended to fourteen feet.
This is a very unique screed in so much that the entire mat surface is compacted. The screed
extensions are not strike offs, they have compacting wear plates attached to them.
The screed depth controls are attached to the hopper frame by two spherical, self-
aligning, cast iron nuts. This is to insure effortless depth adjustment regardless of the paving
setting. The screed assembly may be adjusted to a three inch crown or three inch invert.
The crown adjustment is made by ratcheting the adjustment lever on the middle of the screed.
Because of the tight machining tolerances of the connecting joints between the screed
and the hopper, accuracy of the mat thickness can be accomplished. When an adjustment or
setting is made on the depth control screw, a rapid change in mat thickness is accomplished
and can be maintained with ease. In most cases, when a desired mat thickness is obtained,
little or no compensation will need to be made.
UNDERCARRIAGE
The independent mounted boggy assemblies contribute largely to an accurate and
successful paving operation. The independent boggies are precisely located, and mounted
into the hopper frame. This offers the capabilities to pave at different depths on either sides
of the screed assembly and offers an accurately paved mat.
To change the paving depth from five to ten inches, in lieu of the standard zero to five
inch setting, it is necessary to remove and flip the boggy assemblies over, and reinstall them
into the support legs.
Two double acting cylinders power the hitch arms that attach to the dump truck to pull
the paver. The hitch arms have three position adjustments for the rim rolls and side rolls that
will permit attaching to most trucks.
The screed assembly on the JMG Equipment Company tow type asphalt pavers have

Paver set up and operation
When the paver is on the job site and before asphalt is dumped into the hopper, the machine
should be sprayed with cleaning fluid (with the spray cleaning system furnished) inside th hopper,
on the bumper rollers, augers, screed extensions, and under the screed.
Check the screed for crown, valley, or level condition. This is accomplished by checking the
indicator for the “0” setting and by sighting the underside of the leading edge of the screed. Adjust
the screed to proper position with the ratchet on the center of the screed. Detach chains holding
the paver to the truck by raising the truck bed. Start the engine, move the hopper wings and tow
hitch arms to the open position.
Connect the tow hitch arms in the rear wheels of the truck. Excessive pressure should not
be applied to the tires; retract the hitch arms only until the side rolls touch the tires of the truck.
To move the paver in position for the first paving pass, put the tailgate hook in the center of the
tailgate of the truck and hook the screed lift chain into the tailgate hook. Raise the screed off the
ground about four inches.
Before beginning to pave, it is essential that the screed be elevated a distance equal
to the desired mat depth plus enough extra height to allow for the mat compaction by rolling.
This is done by placing “ starting blocks” under the screed. If a finished mat depth of two
inches is desired, starting blocks two and one quarter inch thick would provide a suitable
starting height. The starting blocks should be at least as long as the width of the screed wear
plate, and placed length wise with the direction of travel. Place one block under each end of
the screed. If necessary, place additional blocks beneath the screed extensions. This
placement will provide the screed wear plate with bearing surfaces that are essentially
parallel with the grade. Lower the screed, bringing it tow rest upon the starting blocks. With
the screed in this position rotate the screed depth cranks until the screed wear plate is
completely flat on the starting blocks and free rotary travel (no resistance) of the screed
depth crank is attained. Rotate the screed depth cranks an additional one half turn clockwise.
When paving begins check mat depth and adjust screed depth cranks until desired mat depth
is attained. Use the screed depth gauge as a reference point only.
To adjust the PavMaster by Gilcrest paving width from the standard eight feet, simply extend
the hydraulic screed extensions to the desired paving width. The screed extension controls are
located on each operator’s console.

Before beginning to pave with bituminous materials, the screed
should be preheated. This helps to prevent the hot mix from sticking
to a cold screed plate, and produces a smooth, tight mat surface.
Preheating should be performed if the machine sets a long period
of time between loads allowing the screed plate to cool. At the
beginning of the day allow 15 minutes for heat up of a cold screed.
Shorter periods of time will be sufficient when the screed is sitting
on warm material. When heating the screed, the extensions should be
retracted full in to insure proper heating of the extension wear
plate.
IMPORTANT: Avoid overheating of the screed which may
warp the screed wear plate and frame.
Never refuel paver with screed heaters lit and operating.
Never use the wash down system when the screed heaters
are lit or operating.
Do not open propane valves to the screed burners unless flame is
present to light the burners. An accumulation of unburned gas could
result in explosion. Do not allow smoking when lighting propane fired
screed burners. If screed heaters should go out for any reason, never
attempt to relight until excess propane is ventilated from the screed
burner chamber.
Failure to observe the above could result in fire, personal
injury or death!!!
To light the screed heaters, turn the valve on top of the propane
tank. Adjust the pressure valve until the gage reads between six and
eight psi. Hold an open flame next to the holes in one of the burner
nozzles and open the burner valve. Repeat the previous steps to light
the opposite burner.
the screed extensions and may be used in two different ways. When not
paving adjacent of previously paved areas, the strike off shoes should
be free floating. Loosen the jam nuts on the outer most hex head
bolts, and rotate the bolts counter clockwise until the strike off
The PavMaster’s screed strike off shoes are located on the end of
10
Loosen the jam nuts on the two vertical five inch long all thread
hex head bolts, and rotate the bolts clockwise until maximum vertical
movement of the screed strike off shoe is available. Retighten the jam
nuts to secure the long hex head bolts. The screed strike off shoes
are now full floating, and will maintain a positive edge of the mat at
any paving depth.
When paving next to a previously paved area, if a smooth joint is
to be made, the screed strike off shoe on the side where the joint is
being made should be adjusted so that it is level with the bottom of
the screed wear plate and secured. To secure the screed strike off
shoe, simply reverse the steps described previously to make the shoe
full floating.
Set tailgate chains on truck to desired opening of the tailgate.
Raise the truck bed sufficently to dump into the paver hopper. Engage
the augers at this time in the "Automatic" position. Open gates
sufficently to allow material to the augers. It is not necessary to
open the gates to full open position. The augers are visible from the
rear of the machine and a constant check on material in front of the
screed can be observed continuously. This will be very helpful when
operation of the augers is in the "Manual" position. When the augers
are operating in the "Automatic" position, the augers will engage and
disengage when the material flow is needed.
Move the paver forward four or five feet and stop at this point.
Check the thickness of the pad. This will allow time for the screed
extensions to warm up properly to provide for a smoother mat finish.
When you approach the end of the paving pass, observe the augers
and the amount of material in front of the screed. Within a short
timr the operator will be able to close the gates, and control the
amount of material in front of the screed to match within a few inches
of the previous mat. No tailing of the pad and virtually all clean up
at the end of the pad is eliminated.
Hook the screed lift chain in the tailgate hook and raise the
rear of the paver off the pad. Caution should be taken when
approaching the end of the pass to minimize the amount of materia in thel
hopper. This will make it easier to maneuver the machine to the next pass.
If the width of the required pass is less than eight feet, the
pull can be lapped over the previous pull. The screed on the lapped
side of the paver is to be set on "0" and the screed extension fully
retracted. The compaction of the screed should erase any marks in the
asphalt mat.
shoe will move easily. Retighten the jam nuts to secure the hex head
bolts.

Cleaning / Wash Down
must be cleaned and washed down with diesel fuel at the end of each
work day while the machine is still warm. Daily clean up of the paver
can significantly increase the life of components in the material
handling areas and reduce many mat problems. Abrasive materials which
accumulate in bearing, auger, and hopper areas can break loose and
produce tears in the mat as they pass under the screed. All residual
asphalt materials should be removed from the paver, especially in the
material handling areas, and the surfaces sprayed to "terminate" any
remaining residue. This leaves a petroleum film on surfaces to reduce
the potential for material sticking the next time the paver is used.
The clean up and wash down procedure should be performed away
from the paving site. The paver should be moved to a designated area
and all functions shut off.
WARNING: Diesel fuel is both flammable and slippery, extreme care must be
exercised during the clean up and wash down procedure to avoid fire or
personal injury.
Never wash down the machine while burners are operating. This could
result in fire or explosion!!!
Never smoke or allow other persons who are smoking into the area during
wash down. This could result in fire or explosion!!!
Never stand in the hopper or on or around the augers while the paver is
operating.
Run the augers only when required to gain access to all surfaces and only
after personnel are out of the material handling areas.
operator's console. The ON/OFF toggle switch is located on the right
console. The wash down switch should be turned on only immediately
before wash down is to begin, and off immediately after it is completed.
To ensure proper performance and maximum life of the PavMaster, it

designed to provide many years of reliable operation if properly
maintained. The following information will aid in proper maintenance.
1) During the first few hours/days of operation with a new machine,
check fasteners (bolts, nuts, ect.) on high vibration areas to ensure
tightness. Occasionally these will become loose while a machine is
starting up. Tighten any loose fasteners you might find. This should
not continue after 10 to 20 hours of operation, (hitch arm bolts,
hopper wing mounting bolts, ect.).
2) Replace fluids and filters as recommended in the Power Unit Maintenance
and Lubrication Points sections.
3) Refer to and follow recommendations in the Wear Check Points section.
4) Check and maintain all fluid levels daily.
5) Clean asphalt residue from hopper, screed augers, and anywhere else
it accumulates after each use. (Refer to Cleaning/WashDown Section)
6) Repair (touch up) paint chips, nicks and worn spots to prevent
exposing raw steel to the elements to help prevent rust.
7) Replace any decals that have been damaged, worn, or painted over.
