3. OPERATION
WolfPac
2500
3.9 FORWARD / REVERSE / NEUTRAL
The forward/reverse lever should be aligned with
"NEUTRAL" on the console when the roller is moving
neither forward nor backward with the engine running.
The neutral interlock switch should NOT allow the
engine to start unless forward/reverse lever is in
NEUTRAL.
3.10 THROTTLE
The throttle control lever must be tight and it should
operate smoothly with light hand pressure (10 lbs.
approximately). For best performance, run engine at
full throttle.
3.11 FUEL SHUT-OFF VALVE
BEFORE TRANSPORTING, TURN THE FUEL
VALVE TO THE OFF POSITION OR HARD
STARTING AND ENGINE DAMAGE MAY
OCCUR. NEVER PUSH OR PULL THE
ROLLER.
3.12 DRUMS
Front and rear drums can be filled with water. There
are two plugs. One plug to fill with water and the other
to drain. Drain water from drum if temperature is
expected to drop to 32 degrees Fahrenheit (0 degrees
Celsius).
3.13 WATER TANK / SPRINKLERS
Fill the tank with clean water. The water tank holds 30
US gallons. Dirty water will clog the sprinkler bars.
The roller is equipped with front and rear sprinklers.
To turn on sprinklers, pull the sprinklers lever out.
Water flow is adjustable by varying the position.
If the water tank is subject to freezing temperatures, all
the water lines and the water tank must be drained by
draining through sprinkler tubes or by removing the
drain plug in the bottom of water tank.
3.14 COCOA MATS / SCRAPERS
Cocoa mat, located on both drums, must make uniform
contact across entire width of drum to ensure even
application of water from the sprinkler system. The
scrappers prevent dirt and asphalt from collecting.
3.15 ASPHALT COMPACTION TIPS
Make sure drums are coated with just enough
water to prevent asphalt sticking to the drums.
Two passes should be sufficient if the asphalt
temperature is about 285° F or greater.
Do not let asphalt stand for an extended time
before rolling.
As soon as the asphalt will support roller
without shoving or causing excessive
movement of the mat, the operator may
proceed with the breakdown pass. If the mat
shows cracks or splits perpendicular to the
roller path, let mix cool 3 to 5 minutes before
continuing.
Change directions and speed slowly to avoid
tearing the mat.
To assist edge compaction and confinement,
leave 4" uncompacted and allow to cool
slightly before finishing.
When possible, begin breakdown pass
downhill and return uphill on same pass before
moving over to next pass.
Compact on low edge first making breakdown
pass and immediately reversing on breakdown
pass before moving toward high edge of the
second pass.
On cool, thick or coarse mats, make as many
intermediate and finish passes as necessary to
achieve desired compaction and surface finish
but avoid overcompaction (aggregate
fracturing).
