The following instructions are intended to assist the user in the installation of the hose reel kit for use on the
DIS185SSI4F air compressor. Please read all installation instructions before installing the kit.
REQUIRED TOOLS
Power drill with 13/64", 11/32", and 3/4" drill bits
Metric/SAE ratchet set
Metric/SAE socket set
Wire cutters/strippers
1/2" thread sealant tape
Scriber or equivalent tool
PARTS
Verify that all parts are accounted for. See Figure 1 and Table 1.
Only a qualified service technician with proper training
should perform this installation. Follow all shop safety rules
when performing this installation.
AIR COMPRESSOR SAFETY
DANGER
NEVER operate the equipment in an
explosive atmosphere or near combustible
materials. An explosion or fire could result,
causing severe bodily harm or even death.
WARNING
NEVER disconnect any emergency or safety devices.
These devices are intended for operator safety.
Disconnection of these devices can cause severe injury, bodily harm or even death. Disconnection of any of
these devices will void all warranties.
CAUTION
NEVER lubricate components or attempt service on a
running machine.
1. Make sure the air compressor is turned OFF and the
engine is cool.
2. Place the air compressor in an area free of dirt and
debris. Make sure it is on secure level ground with
chock blocks underneath each wheel to prevent it
from rolling.
BATTERY DISCONNECTION
1. Open the battery-side cabinet door to access the
battery (Figure 2).
CABINET DOOR
Fuels, fluids, coolants, lubricants, and battery electrolyte
used in the air compressor are typical of the industry.
Care should be taken to avoid accidental ingestions and/
or skin contact.
Make sure the air pressure reads zero before performing
any maintenance.
ENGINE SAFETY
CAUTION
NEVER touch the hot exhaust manifold,
muffler or cylinder. Allow these parts to cool
before servicing the equipment.
BATTERY SAFETY
DANGER
DO NOT expose the battery to open flames,
sparks, cigarettes, etc. The battery contains
combustible gases and liquids. If these
gases or liquids come into contact with a
flame or spark, an explosion could occur.
2. Disconnect the negative cable (BLACK) from the
negative (−) terminal on the battery. See Figure 2.

DRAINING THE FUEL TANK
If there is fuel in the fuel tank, it must be drained before
performing this installation.
1. Prepare a container (Figure 3) into which to drain the
fuel.

DRAIN BOLT
CONTAINER
Figure 3. Draining the Fuel Tank
2. The fuel drain bolt (Figure 3) is located on the fuel
tank side of the air compressor at the rear of the trailer
frame. Loosen the bolt to allow any fuel inside the tank
to drain into the container. Retighten the fuel drain bolt
when finished.

NEW BUMPER INSTALLATION
1. The fuel tank base cover (Figure 4) must be loosened
to allow access to the bumper hardware. Loosen the
seven hex head bolts securing the fuel tank base
cover to the frame. DO NOT remove the bolts nor the
cover itself.
