Changing hydraulic hoses

» Hydraulic hoses must be regularly inspected.
» Hydraulic hoses should be replaced immediately in the event:

that the outer mantle has been damaged (e.g. graze marks, cuts, tears),

that the outer mantle has become brittle (tears in the hose material),

that under pressurized or non-pressurized conditions, deformation occurs which is not due
to the original shape of the hose,

that deformation occurs where the hose is bent (e.g. pressure points, bending points, the
outer mantle is detaching, bubble formation),

of leaks,

that a component has not been installed according to the guidelines,

that the hydraulic hoses become separated from the couplings,

corrosion of the couplings which reduces function and rigidity,

damaged or deformed couplings which reduces function and rigidity.

Only original replacement hydraulic hoses from TENNANT guarantee that the proper hose
type is used at the applicable place.

Working on the engine

» Only drain cold engine oil.
» Collect spilt and drained-off engine oil in a container and dispose of in an environmentally-

friendly manner.

» Place used oil filters and other oil-covered materials in a separate, labelled container and treat

them in an environmentally-friendly manner.

Working on electrical parts

» Remove the battery clamps from the battery and cover them with insulating material before

working on the electrical components.

Never use fuses of higher amperage and do not connect fuses with wire
Fire hazard!

Working on the battery

» No unprotected fire and no smoking.
» Avoid acid from coming into contact with clothing or the skin.

In the event of acid injuries, rinse well with clean water
and contact a doctor.

»  Never place any tools on the battery.
»  When recharging the battery, remove the caps to avoid a build-up of explosive gases.
»  Treat old batteries in accordance with legal stipulations.

Working on the fuel system

» No unprotected fire and no smoking.
» Avoid spilling fuel. Catch spilt fuel and prevent it from seeping into the ground.
