SAFETY INSTRUCTIONS
General information
Avoid personal injury. Read the following personal safety
instructions and insist that everybody who works with you
or for also complies with the instructions.
Only use tools which have been approved by the manu-
facturer for use with the loader.
Guards
This manual contains a number of illustrations which
show the guards removed, to give a better picture.
Never use the machine with the guards removed. If a
guard has been removed for service/repairs, re-install
the guard before the machine is taken back into service.
•
Warning decals
Warning decals are installed at various places on the loader
and the tools. Localise, read and find out what the decals
mean before the loader and the tools are used. See section
"Location of warning decals".
Do not cover or remove any warning decal. If a
warning decal is missing or illegible, replace it by a
new decal. New warning decals are available as spare
parts.

occur if the instruction is not followed. An
accident could lead to personal injury.
The following texts and instructions do not refer to personal
safety, but are used consistently in the instruction manual,
to provide tips about operation or service of the machine.
Important: Means that an accident could occur if the
instruction is not followed. The accident might lead to
damage to property or the process, or personal injury.
Note: Refers to extra information which could facilitate
understanding or completion of a certain task.
Symbol explanation

Risk factors during service
Do NOT do any service on the loader when the tractor
engine is running or hot, or when the machine is moving.
Before servicing loader/tractor, remove key and place
transmission in park position.
If loader is disconnected from tractor, tool must be
attached to loader for parking. Park loader on solid
level ground.
•
•
BWARNING: Always lower the loader to the
ground.
Lower loader and tool to ground.
Apply handbrake securely.
Move gear lever to neutral or park position.
Shut engine off.
Remove the ignition key.
Cycle control lever through all positions to unload
hydraulic pressure.

Safety instructions
9020013100a.indd
The loader is equipped with a stop valve above the control
valve on the right of the loader.
This should be turned closed "position" during service
work, or when the loader is left in the lifted position for
any length of time for other reasons.
BWARNING: This valve may NOT be used
when working in the loader's lift cylinders or
associated lines. In such cases, the loader
must be lowered to the ground. Turn off
the tractor's engine, depressurise the oil
pressure with the operating control before
disconnecting any couplings or doing any
other work on the hydraulics - oil under high
pressure can cause severe injuries.
When working on the loader's hydraulic system, release
hydraulic pressure by moving all hydraulic controls to
all positions a number of times once the engine has
been shut off.
Do NOT use the loader to lift the tractor during service
on the tractor or the loader.
•
•
Turn the stop valve to closed position during service work.
NEVER use your finger or hand to search for leaks.
BCAUTION: Be on your guard against pressu-
rised hydraulic fluid. NEVER use your finger
or hand to search for leaks. The fluid which
flows out from small holes can be almost
invisible. Use a piece of wood or cardboard
instead.
Undo hydraulic couplings slowly. Keep your hands and
fingers away from loosened couplings.
Get medical attention at once if fluid penetrates your
skin. Serious reactions and/or infections can rapidly
occur if the oil is not removed at once by surgical
operation.
Spare parts
When spare parts are needed for service and mainte-
nance work, only use original spare parts to restore the
machine to its original quality standard.
The manufacturer declines all responsibility if non-
approved spare parts or tools are installed, and for the
damage which might occur if such non-original spares
are used.

INSTALLATION
Checking the subframe hardware
Check that all hardware are tightened to the specified
torque, first time after 10 hours of operation and then every
50 hours of operation. Please refer to the table below for
torque values.
Tightening torques - Hardware
Torque all the hardware on the subframe and all fasteners to
the values specified in the table below, except in the cases
where the tightening torque is specified in the assembly
instructions.
The torques specified below apply to clean, dry threads.
Lubricated threads can mean that the fastener is over
torqued. Damaged or dirty thread can cause torque values
which are too low.
A torque amplifier can be needed when tightening screws to
high torque values.

Delta subframe preparation
Consult both the safety and the installation instructions
before beginning any installation.
Before you begin to install the Subframe, ensure that you
are equipped with all of the proper tools and parts required
to attach the subframe to the tractor.
If any defect of the Subframe material, workmanship or
mounting is observed, contact Alo technical support. If the
Subframe does not fit properly, this issue should be addres-
sed immediately so that we are made aware of the potential
problem, and are able to instruct you on how to proceed.
Before mounting either of the latest loader ranges from
Quicke or Trima to the new Delta™ subframe, you must
carry out the following procedure.
All paint must be removed from the machined surfaces:
A. Machined Saddle
B. Front Face and Lip
C. Loader
Remove all paint from tractor casting, and any excess paint
from subframe to ensure a secure contact. A chasing tap
may be required to clean out the tractor casting.
If a bolt will not start into its designated hole, check that the
hole is clean and free from paint. Also, make sure that the
bolt is being used in the correct hole. If there are any
problems screwing in the bolt, DO NOT attempt to force it
in; this could strip the hole of its threads.
Use an overhead hoist to raise the Subframe up to the
tractor. Be careful to protect the tractor hood and platform
from damage.
Start some of the bolts into the tractor. Once you are sure all
of the bolts will thread into their proper holes, begin
tightening the bolts so that they will support the Subframe.
All paint must be removed from the machined surfaces: 
