Dear Owner,
Thank you for purchasing a HARDI®product and welcome to the ever-
increasing family of HARDI®sprayer owners.
Our sprayers and accessories are rapidly becoming a familiar sight
on North American farms. We believe that this results from growers
becoming increasingly conscious of crop protection input costs and the
vital need for cost effective application equipment.
Please take the time to thoroughly read the Operator’s Manual before
using your equipment.You will find many helpful hints as well as
important safety and operation information.
Some of the features on your FORCE™ boom were suggested by
growers. There is no substitute for “on farm” experience and we invite
your comments and suggestions. If any portion of this instruction book
remains unclear after reading it, contact your HARDI®dealer or service
personnel for further explanation before using the equipment.
For Product, Service or Warranty Information:
- Please contact your local HARDI®dealer.

1.0 INTRODUCTION
The HARDI®FORCE™ boom is constructed from a 3-dimensional
design offering exceptional strength, stability and low maintenance.
80', 88' and 90' FORCE™ booms have Bi-fold wings (also 110' prior to
2002), while 100', 120' and 132' FORCE™ booms have Tri-fold wings.
The trapeze and link arms make the FORCE™ boom friction free with
less service and wear on the parts.
The FORCE™ boom is offered with an HZ type of hydraulic system
that features simultaneous inner wing fold and outer wing fold as well
as individual wing tilt. For "closed center" tractor hydraulics systems, an
optional "DH" (Direct acting Hydraulics) control box is available. Both
systems require one single acting and one double acting hydraulic
outlet on the tractor and a 12V-power supply for the in-cab mounted
controls.
The FORCE™ boom is fitted with triplet nozzle bodies that can be set
up for a variety of spraying applications.

spraying season. Failure to do so may result in possible over or
under application of spray solution which may drastically affect crop
production or lead to personal injury.
2. Before starting the engine on the tractor unit, be sure all
operating controls are in the off or neutral position, including (but
not limited to) the P.T.O. shaft and or spray controls. Be sure the
tractor power train is disengaged.
3. Operate spray and boom functions only when seated in the
operator’s seat.

7HARDI® FORCE™ BOOM OPERATOR’S MANUAL
4. One of the most frequent causes of personal injury or death
results from persons falling off or being run over. Do not permit
others to ride on or in. Only one person - the operator - should be
on the machine when in operation.
5. Before leaving the tractor seat, stop the engine, put all controls
in neutral, and put the transmission control lever in the park position
or neutral with the brakes locked. Read the tractor operation manual
for added safety precautions.
6. P.T.O. driven equipment can cause serious injury. Before
working on or near the P.T.O. shaft, servicing or cleaning the
equipment, put P.T.O. lever in the DISENGAGE position and stop
the engine.
7. Do not fold or unfold boom near overhead wires. Serious injury
or death could result if contact is made with electric wires.
8. Keep hands, feet & clothing away from moving parts.
9. Wear relatively tight and belted clothing to prevent from being
caught on some part of the machine.
10.Slow down when turning, especially with boom extended.
11.Always keep children away from your sprayer and/or tractor unit.
12.Before transporting the sprayer ensure that the boom is fully folded
and fully locked into transport rests and stops. Ensure all locking
devices are fully engaged whether hydraulic or mechanical.
13.Slow moving tractors and spray equipment can create a hazard
when on public roads. Avoid personal injury or death resulting from
any accidents by using flashing lights. Local regulations may require
installation of flashing warning lights.
14.Avoid injuries from high pressure fluids penetrating the skin by
relieving system pressure before disconnecting hydraulics or other
lines. Ensure all fittings are tight before applying pressure to the
system.
15.Understand service procedures before undertaking any
maintenance. Never lubricate, service, or adjust the spray boom
while its operating. Securely support any components before
working on them.
16.Keep all parts in good condition and properly installed. Fix damaged
parts immediately. Replace worn or broken parts. Remove
excessive buildup of grease, oil, or debris.

8 HARDI® FORCE™ BOOM OPERATOR’S MANUAL
2.3 Handling Chemical Products Safely
1. Direct exposure to hazardous chemicals can cause serious
injury. These chemicals can include lubricants, coolants, paints,
adhesives and agricultural chemicals. Material Safety Data Sheets
(M.S.D.S.) are available for all hazardous chemicals which inform
the user of specific details including, physical and health hazards,
safety procedures, and emergency response techniques.
2. Protective clothing such as rubber gloves, goggles, coveralls
and respirator must be worn during operation. All protective clothing
should be kept in excellent condition and cleaned regularly or
discarded.
3. If chemicals come in contact with any exposed skin areas,
wash immediately with clean water and detergent. Never place
nozzle tips or any other components that have been exposed to
chemicals to mouth to blow out obstructions. Use a soft brush to
clean spray nozzles.
4. Dedicate an area to fill, flush, calibrate and decontaminate
sprayer where chemicals will not drift or run off to contaminate
people, animals, vegetation, water supply, etc. Locate this area
where there is virtually no chance of children being in contact with
this residue.
5. Decontaminate equipment used in mixing, transferring,
and applying chemicals after use. Follow the instructions on the
chemical label for the correct procedure required. Wash spray
residue from outside of the sprayer to prevent corrosion.
6. Extreme care should be taken in measuring spray products.
Powders should be used in suitable sized packages or weighed
accurately. Liquids should be poured into a suitable graduated
container. Keep chemical containers low when pouring. Wear a
filtered respirator and let the wind blow away from you to avoid dust
and/or splashes contacting the skin or hair.
7. Store chemicals in a separate, plainly marked locked building.
Keep the chemical in its original container with the label intact.
8. Dispose all empty containers after rinsing in accordance with
local regulations & by-laws. Dispose of all unused chemicals and
left over fertilizer in an approved manner.
9. Keep a first aid kit and fire extinguisher available at all times
when handling chemicals.
