as earm ffs or earpl gs (mainly when working
with NEUMATIC machines).
Safely operating the eq ipment req ires
the operator’s f ll attention. Do not wear radio or m sic
headphones while operating the machine.
SAFE OPERATION

AVOIDING HIGH PRESSURE LEAKS
Leaking fl id nder press re can penetrate
the skin ca sing serio s inj ry.
Avoid the hazard by relieving press re
before disconnecting hydra lic or other lines.
Tighten all connections before applying
press re to the circ it.
Search for leaks with a piece of cardboard.
Do not p t hands or body near high press re leaks.
If, in spite of this preca tion, an accident occ rs, see a specialist doctor immediately.
PRACTISING SAFE MAINTENANCE
Understand service proced re before operating the machine.
Keep area clean and dry.
Never l bricate, service, or adj st the machine
while it is moving. Keep hands, feet, and clothing
away from power-driven parts.
Disengage all power and operate controls to relieve
press re. Lower the eq ipment to the gro nd.
Stop the engine. Remove the key.
Allow machine to cool.
Sec rely s pport any machine elements
that m st be raised for service work.
Keep all parts in good condition and properly
installed. Fix damage immediately.
Replace worn or broken parts.
Remove any b ild p of grease, oil, or debris.
Disconnect battery gro nd cable (-) before making
adj stments on electrical systems or welding on machine.

USING A SAFETY CHAIN
A safety chain will help control drawn eq ipment
sho ld it accidentally separate from the drawbar.
Using the appropriate adapter parts, attach the
chain to the tractor drawbar s pport or other
specified anchor location. Allow only eno gh
slack in the chain to permit t rning.
Use a chain with a strength rating eq al to or
greater than the gross weight of the towed machine.
Do not se safety chain for towing.
SAFELY TRANSPORTING THE MACHINE
Shift tractor into the lowest gear when transporting
down steep slopes or hills.
Make s re that lights and flashing warning lights
are easily visible from behind.
Stop slowly.
Bear in mind the width of the machine yo are
transporting.
Empty fertilizer and seed boxes completely
before transporting the drill.
DO NOT EXCEED maxim m speed of 10 mph
(16 km/h) if drill is not empty.
DO NOT EXCEED maxim m speed of
10 mph (16 km/h) when transporting two
hitched nits.
Lock p cylinders of hydra lic lifting system
before transporting the drill. Hydra lic fail re
can allow machine to fall rapidly.

KEEPING RIDERS OFF THE MACHINE
Only allow the operator on the machine, keep riders
off.
Riders on machine are s bject to inj ry s ch as
being str ck by foreign objects and being thrown
off the machine.
Riders also obstr ct the operator's view res lting
in the machine being operated in an nsafe manner.
TOWING LOADS SAFELY AND SLOWLY
Braking f lly from the transporting speed can
ca se the towed load to lose control and overt rn.
Red ce speed if towed load speed is greater
han the tractor weight and the towed load has no
brakes.
Observe these recommended maxim m road
speeds and weight.
* When towing a load eq al to or lower than
the tractor weight, do not travel faster than 20 mph
(35 km/h).
* Red ce speed to 10 mph (15 km/h) when towing
a load whose weight is p to the do ble the tractor weight.
* Do not tow loads that do ble the tractor weight.
* Use additional ca tion when towing loads nder
adverse s rface conditions, when t rning, and on slopes.

HANDLING PESTICIDES AND FERTILIZERS
SAFELY
Keep powders off yo r skin or hair.
Keep containers in a low position when po ring.
Let the wind take d sts, smokes or spray away from
yo when mixing with seeds or filling tanks.
Wear a filter respirator if d st cannot be avoided.
Wear safety glasses to protect yo r eyes.
Wash exposed skin areas freq ently.
DO NOT allow pesticides to remain on yo r skin.
Do not smoke when handling pesticides.
Always dispose of sed containers or n sed pesticides
properly. Keep treated seeds and fertilizers apart.
Store pesticides in clearly labeled places and in a
closed b ilding.

SERVICING AND MAINTENANCE
n
nn
n CHECK the tightness of all bolts during the first seven (7) days of operation.
n
nn
n GREASE all nipples and lubricate all mechanisms before starting the machine.
SEE frequency of greasing required.
n
nn
n OIL all machine chains at regular intervals. They must not lack lubrication.
n
nn
n DO NOT park the machine when openers are in the ground once the task is
finished, since the openers and springs will have to bear the load. The machine
must rest on the cylinder locks with the hydraulic circuit discharged.
n
nn
n DO NOT transport the machine with a loaded box, the maximum transporting
speed is 10 mph (15 km/h).
n
nn
n CLEAN seed boxes properly and meters regularly leaving them free of seeds.
n
nn
n FERTILIZER COMPARTMENT: Clean compartment thoroughly. In cold weather
and if the drill is to be used the following day, it would be convenient to fill up the
compartments the night before and cover the machine with a canvas. This will
prevent humidity condensation within the compartment. Clean all elements
thoroughly when planting is complete if elements are not to be used for a long
time. Rinse with water and apply fuel oil or a light lubricant to avoid the corrosive
effects of fertilizers. For correct system operation, use quality products with no big
lumps. For good results, choose products with humidity-resistant formulation. ASK
YOUR PROVIDER.
n
nn
n The words LEFT-RIGHT-FRONT and REAR as used in this manual are
determined looking the machine from behind.
