Hydraulics - standard joystick handle
Installation of handle
1. Attach the control handle/joystick

to the hydraulic
lever that operates the double acting outlet to be
used. The universal mounting bracket
B
is very
flexible and a number of different mounting positions
can be used.
2. Connect the plug
C
to the tractor’s 12V power
system. Try to hook-up the handle as close as
possible to the battery power supply. HARDI
®
recom-
mends using an electric distribution box (ref. no.
817925) to ensure a good power supply to various
12V attachments.
Note:
Check with your dealer or tractor operator’s
manual for the best location to hook up the 12V sys-
tem.

BE SURE TO HOOK UP HYDRAULIC LINES
PROPERLY!
ENSURE HYDRAULIC LINES HAVE NOT BEEN
DAMAGED DURING SHIPPING.
ESCAPING HYDRAULIC FLUID UNDER PRESSURE
CAN PENETRATE THE SKIN CAUSING SERIOUS
INJURY. AVOID THIS HAZARD BY RELIEVING
PRESSURE BEFORE DISCONNECTING HYDRAU-
LIC LINES.
ENSURE ALL CONNECTIONS ARE TIGHT BEFORE
APPLYING PRESSURE, SEARCH FOR LEAKS WITH
A PIECE OF CARDBOARD NOT YOUR HANDS!
IMPROPER HOOK-UP CAN CAUSE DANGEROUS
BOOM MOVEMENTS AND/OR DAMAGE TO THE
SPRAYER HYDRAULICS.
DO NOT ALLOW ANYONE NEAR A HYDRAULIC
BOOM IN OPERATION.
ALWAYS SHUT TRACTOR OFF WHEN CONNECT-
ING, SERVICING OR ADJUSTING BOOM.
Make sure that the hydraulic couplers are clean before
connecting to the tractor’s remote outlets.
IMPORTANT!
Due to the variation in tractor
hydraulic systems and capacities, care should
be exercised when initially operating the
sprayer hydraulic cylinders. It is advisable to adjust the
hydraulic flow control down to the minimum rate before
operating the system. Adjust/increase the flow control
after the system is bled of any air, if necessary.
