Moving the unloaded shifting carriage:

Be particularly careful when wheeling the

unloaded shifting carriage backwards - it can

easily topple over!

Lifting and lowering (with/without

load)

Der Hubwagen TG ist mit einer von Hand bedienbaren

Hydraulikpumpe ausgestattet.

C Safety catch

Stellungen des Zuggriffs

Normal lift

To shift the pump into the high-pressure position, lift the

trigger handle until the safety catch engages. In this

position, the rapid-action pump piston is disengaged.

With every stroke of the pump, the slot-in lifting profile

is raised 17 mm. Loads of up to 1000 kg can be raised

in this position.

Lowering

To lower the load, slowly pull up the trigger handle.

Slowly lower both Shifting carriages TG simultane-

ously. When this is done and you let go of the trigger

handle, this is automatically returned to the middle

position.

Hydraulic system - general notes

Venting

To vent the lifting cylinder, pump the slot-in lifting profile

all the way to the top and then rapidly lower it again.

Safety precautions

The overpressure valve is set in such a way that the

max. capacity of the Shifting carriage TG is 1000 kg.

It is forbidden to tamper with the setting screw on the

overpressure valve.

Original Operating Instructions Shifting carriage TG

Maintenance

Change the hydraulic oil

after every 1000 operating hours

at least 1x a year

The hydraulic system is filled with a special low-temper-

ature oil that has a viscosity in accordance with ISO VG

10 (e.g. Aero Shell Fluid 4). The oil is additivised with:

Wynn's Hydraulic System Concentrate.

This concentrate is added in a mixing ratio of 2.5:100.

The concentrate lessens friction and wear-and-tear,

and gives protection against corrosion. A ready-to-use

hydraulic-oil / additive mixture is available from your

dealer.

Filling-quantity of hydraulic oil: 0.75 l. If the slot-in lifting

profile can be raised to the highest position, then there

is sufficient oil in the system.

CAUTION

Hydraulic oil is harmful to the environment!

For this reason, always properly seal any

leaks immediately!

Intercept any leaking hydraulic oil and dis-

pose of it in accordance with the applicable

regulations!

Maintenance (general remarks)

Cleaning & maintenance

Clean the Shifting carriage TG whenever it has been

made dirty. Pay particular attention to the hydraulic sys-

tem, the moving parts of the guide mechanisms, the

bearing surfaces of the supporting frame, and the

swivel casters.

Before starting up at a new site

Lubricate with grease via the lubricating nipples pro-

vided.

Lubricate the load chain and the deflection pulleys

with lubricating grease.

Once a year, when lubricating the chain, inspect it care-

fully for any signs of alteration and damage.

Troubleshooting

The load is not being lifted, even though you

have made several attempts to "pump"

Possible causes:

Load too heavy (> 1000 kg)

Not enough hydraulic oil

Hydraulic tubing is leaking

Air trapped in the hydraulic system

Valve control system not working (low-pressure

valve core)

Faulty over-pressure valve (integrated in the low-

pressure valve core)

The valve-face does not shut tightly (high-pressure

valve core)
