General Safety Guidelines
SAFETY WARNING!
To prevent possible eye injury, always
wear SAFETY GLASSES while
operating or servicing the equipment.
SAFETY WARNING!
Use genuine factory parts or parts with
equivalent characteristics, including
type, strength and material. Failure to
do so may result in product
malfunction and possible injury to the
operator and/or others.
Fasteners
• Replace locknuts and locking screws if
you can tighten them without feeling
considerable resistance for several
turns before they are completely tight.
Replace them with factory authorized
parts or their equivalent.
• If hardware / fasteners are not secure,
or if some of the hardware is overtightened, equipment failure may result,
posing possible safety hazards.
Gasoline
• Never remove the fuel tank cap or add
gasoline when the engine is running or
while it is hot.
• Never fill the fuel tank indoors (fumes
can collect).
• Wipe up spilled gasoline immediately
and completely.
• Do not store gasoline in a room with
an appliance that has a pilot light to
where electrical appliances or
switches may cause sparks.
• Always store gasoline outdoors in a
safety can (a can which has a flame
arrestor and pressure relief valve in
pour spout).
• Gasoline fumes are heavy and will
sink to the lowest point, collecting and
becoming more and more hazardous.
1 part gasoline in 20 parts air will
explode easily and violently.
• Never store the equipment with
gasoline in the tank inside a building
where fumes may reach an open
flame or spark. Allow the engine to
cool before storing in any enclosure.
• Be certain to provide adequate
ventilation if an engine must be run
indoors - exhaust fumes are
dangerous.
SAFETY WARNING!
Gasoline is extremely flammable and
can be highly explosive.
• Allow engine to cool sufficiently before
refueling.
• Do not allow smoking, open flames or
sparks while performing maintenance
or refueling.
Harper DB1800
Guards & Shields
• Keep all guards, shields and safety
devices in place at all times, removing
only when necessary for service.
• Replace all worn, damaged, unusable,
missing or lost safety shields and
guards before operating equipment.
8
SAFETY WARNING!
Before Operation
Keep all guards and shields in place
and the hood closed during operation
to prevent possible injury or death.
Safety Decals
• If safety related or instructional decals
become illegible or are removed,
replace them immediately.
• If parts that have such decals attached
are replaced, make sure the current
versions of the decals are on the
replacement parts before the machine
is operated again.
• Order new decals from your local
Harper Dealer.
Equipment & Controls
• Before operating this equipment, read
and understand the Owner's Manual.
• Replace damaged or missing safety
decals.
• Wear approved eye and ear protection
and other appropriate safety
equipment while operating the
machine.
• Make sure bolt holding the tongue to
the tow vehicle is secure.
• Before starting the machine, visually
inspect all nuts, bolts and other
fasteners to see that they are properly
secured.
• Make sure both tires are inflated to
manufacturer’s specifications given on
sidewall and wheel lug nuts are tight.
• READ AND UNDERSTAND THE
OWNER'S MANUAL.
• Altering this equipment in any manner
which adversely affects its operation,
performance, durability, or use will
void the warranty and may cause
hazardous conditions.
• Know the location and function of all
controls and how to stop this
equipment quickly in an emergency
before you operate the equipment.
• Keep all nuts, bolts and screws tight to
help ensure safe operation of this
equipment.
SAFETY WARNING!
The DB1800 is not designed for towing
at highway speeds.
During Operation
• Do not allow children to operate this
machine.
• If a foreign object should strike the fan
assembly of the machine and cause
an unusual noise or vibration, shut the
engine off immediately and allow it to
come to a complete stop. Disconnect
the spark plug wire from the spark plug
on the engine, and then do the
following:
1. Inspect for damage.
2. Repair or replace any damaged parts.
3. Check for and tighten any loose bolts,
nuts, fasteners or parts.
SAFETY WARNING!
Harper DB1800
Keep clothing and all body parts away
from rotating parts.
9
• Keep the engine area free of oil, debris
and other accumulations.
• Keep all safety shields and guards in
place and in good working condition.
• Be sure to provide adequate
ventilation if the engine must be run
indoors – exhaust fumes are very
dangerous.
• Periodically clean area around engine
to lessen the possibility of fire.
• Engine governor settings are preset
and should not be altered. Any
change can damage moving parts and
void warranty.
Battery
SAFETY WARNING!
Observe all safety warnings printed on
the battery. Keep away from children.
SAFETY WARNING!
Do not leave machine unattended, or
attempt service or inspection unless
the machine has come to a complete
stop, the engine is off, and the Master
Disconnect is turned off.
SAFETY WARNING!
Contact your local Goossen Dealer or
Harper Industries for assistance if any
part of this manual requires further
explanation. Your safety and the
performance of the Debris Blower may
depend on a clear understanding of the
material contained in this manual.

SAFETY WARNING!
Accidental engine starts can cause
severe injury or death. Before working
on the engine or equipment, disable
the engine as follows:
• Disconnect the spark plug wires.
• Disconnect the negative (-) battery
cable from battery.
Or, visit our website at:
www.harperindustries.com
Set - Up
• Before initial operation, fill the battery
with acid and connect the battery
cables. Unit is shipped without acid
and with cables disconnected.
• Open vent on fuel tank. The engine
will run briefly even if vent is closed.
• Place the control cable onto the tow
vehicle. Be careful not to drag cable.
SAFETY WARNING!
Use protective gear such as gloves
and safety glasses when servicing unit.

Operation
10. To maximize blower efficiency:
• Raise Engine Throttle to high
(Rabbit).
Standard Procedure
1. Wear eye and ear protection at all
times during operation.
2. Fill the tank with unleaded gasoline.
Make sure vent on fuel tank is open.
(Refer to engine manual for gasoline
specs.)
3. With the DB1800 attached to the tow
vehicle, use the leveling link to level
the unit as close to horizontal as
possible. The engine is designed to
operate for extended periods at an
angle of 25 degrees or less.
4. Check engine oil and perform other
routine maintenance as recommended
in the Maintenance section.
5. If necessary, squeeze the primer bulb
to fill the fuel filter with fuel.
6. Before starting engine, turn the Master
Disconnect to the ON position, and
partially turn ignition key clock-wise.
Move the Engine Throttle between low
(Turtle) and high (Rabbit). Point the
nozzle away from any bystanders,
animals or fragile objects.
7. If engine is cold, pull out the choke.
When restarting a warm engine, it may
not be necessary to use the choke.
• Lower the unit when blowing to
the side.
• Raise the unit when blowing
downward.
11. Keep unit in the raised position when
the nozzle is pointed downward to
prevent damage by dragging.
SAFETY WARNING!
Keep by-standers and animals out of
the area of operation to prevent them
from being hit by the air stream or
flying objects.
Operating On a Slope
1. Run up and down steep slopes, never
across the face.
2. Reduce speed on slopes and in sharp
turns to prevent tipping or loss of
control.
3. Use extreme caution when changing
directions on slopes.
Stopping Operation
1. Move Engine Throttle to low (Turtle).
2. Allow engine to idle briefly (30 to 60
seconds) before turning off.
8. Turn the ignition key fully to the start
position and release as soon as the
engine starts. DO NOT TURN THE
STARTER OVER FOR MORE THAN
10 SECONDS.
9. Once the engine is running, gradually
push in the choke and allow engine to
warm up.
Harper DB1800
3. Turn the ignition key and the Master
Disconnect to the OFF positions.
Initial Break-in
After first few hours of use, inspect the
unit for any loose fasteners or fittings.
Tighten according to the Torque Chart.
