During Operation

Never spray in the direction of bystanders – risk

snow, ice, on slopes or uneven ground.
Watch out for obstacles: Be careful of refuse,

tree stumps, roots and ditches which could

cause you to trip or stumble.
To reduce the risk of accidents, take a break in

good time to avoid tiredness or exhaustion.
Work calmly and carefully – in daylight conditions

and only when visibility is good. Stay alert so as

not to endanger others.
Never work on a ladder or any other insecure

support.
When working in open ground and gardens take

special care to avoid harming small animals.
To reduce the risk of electrocution, never work in

the vicinity of live wires or power cables.
Always clean the sprayer before changing to a

different plant protection product.

After Finishing Work

Check all parts of the unit for leaks.
After finishing work, thoroughly clean the unit

and wash your hands, face and, if necessary,

your clothes.
Keep other persons and animals away from the

areas that have been sprayed and do not walk

on them until the plant protection chemical has

dried.

not described in the instruction manual. Have all
