Safety Guidelines

• Use genuine factory parts or parts

with equivalent characteristics, includ-

ing type, strength, and material. Fail-

ure to do so may result in product mal-

function and possible injury to the op-

erator and/or others.

• If hardware is not secure, or if some of

the hardware is over-tightened, equip-

ment failure may result, posing poss-

ible safety hazards.

• To prevent possible eye injury, always

wear SAFETY GLASSES while oper-

ating equipment.

• 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.

Gasoline

SAFETY WARNING!

Gasoline is extremely ammable and can

be highly explosive.

• Always use an approved container for

gasoline.

• Do not allow open ames or sparks

while performing maintenance or refu-

eling.

• Never remove the fuel tank cap or add

gasoline when the engine is running or

while it is hot.

• Never ll 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 switch-

es may cause sparks.

• Always store gasoline outside, in a

safety can (a can which has a ame

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 ex-

plode easily and violently.

• Never store the equipment with gaso-

line in the tank inside a building where

fumes may reach an open ame or

spark. Allow the engine to cool before

storing in any enclosure.

• Be certain to provide adequate ventila-

tion if an engine must be run indoors -

exhaust fumes are dangerous.

Guards & Shields

• Keep all safety devices in place.

• Replace all worn, damaged, unusable,

missing or lost safety shields and

guards before operating the equip-

ment.

• Keep the equipment in good operating

condition.

Safety Decals

• If safety related or instructional decals

become illegible or are removed, re-

place them immediately. New decals

may be obtained from your local Harp-

er Dealer.

• If you replace parts that have such

decals attached to them, make sure

the decals are replaced with current

versions, and are on the replacement

parts before the machine is operated

again.

Operation & Towing

Adjusting the Hose Assist

Properly having the hose assist attached to

the inlet hose will prevent most hose clogs

from happening and maximize the Multi-

Loader’s performance by keeping the hose

straight and perpendicular to the housing.

Adjustments for the hose assist are made

by moving up or down a link at a time on the

chain via the carabiner.

Clogged Hose

Even though an operator has adjusted the

hose assist properly, the hose may still be-

come clogged at some point. To unclog the

hose, begin by straightening the inlet hose

out directly behind where it attaches to the

unit to dislodge the clog. If it still isn’t clear,

turn off the machine and wait for the impeller

to come to a complete stop. Then, remove

the hose from the machine and clear the

debris by hand.

SAFETY WARNING!

The debris may be sharp. Be sure to use

appropriate gloves when clearing debris

from the hose or from the housing/impel-

ler.

The primary types of debris are light lawn de-

bris such as leaves and mulch or light plastic/

paper products.

SAFETY WARNING!

Larger or heavier objects have the ability

to cause damage to the machine and/or to

the operator.

Clogged Housing or Outlet Spout

1. Turn unit off and wait for the impeller to

come to a complete stop.

2. Remove the negative battery cable.

3. Remove the hose and determine where

the clog is located.

4. If the clog is in the housing/impeller, re-

move the clog and reassemble. If not, con-

tinue with 5.

5. If the clog is in the outlet spout, remove

the (8) bots holding the outlet on and take it

off.

SAFETY WARNING!

The outlet spout is heavy. Do not stand

under the spout while removing it.

6. Remove clog from from spout and reat-

tach with the previously mentioned bolts.

Check to make sure that all that was re-

moved from the machine is reassembled and

tightened before resuming operation.

9. Reconnect the negative battery cable and

resume operation.

Adjusting the Belt Tensioner Handle

As the belt stretches with use and time, the

owner can addjust the height of the belt ten-

sioner handle to increase resistance on the

belt by using the

two bolt system

shown in the

picture to the

right.

Towing/Transport

When readying for transport, wrap the inlet

hose around the side of the machine and rest

it on the front bungie bracket and attach the

bungie around the hose. There is a second

bungie bracket on the side to better secure

the hose for transport as well. Lastly, there is

a pin that locks the hose assist arm in place

so that it cannot swing/move while being

towed.
