MAINTENANCE:

 

Important:

 

Both

 

the

 

maintenance

 

and

 

repair

 

of

 

the

 

jack

 

may

 

only

 

be

 

performed

 

by

 

qualified

 

persons,

 

who

 

have

 

sufficient

 

knowledge

 

of

 

the

 

hydraulic

 

system

 

used

 

in

 

these

 

jacks

 

   

Regularly

 

lubricate

 

the

 

moving

 

parts

 

in

 

the

 

wheels,

 

arms,

 

handle

 

and

 

pump

 

roller

 

pin.

 

Only

 

original

 

replacement

 

parts

 

should

 

be

 

used.

 

EXTREMELY IMPORTANT: 

NEVER

 

use

 

brake

 

fluid

 

OR

 

transmission

 

fluid

 

for

 

lubrication,

 

or

 

for

 

filling

 

the

 

hydraulic

 

system.

 

Use

 

ONLY

 

quality

 

hydraulic

 

jack

 

oil

 

for

 

lubrication

 

and

 

filling

 

of

 

the

 

hydraulic

 

system.

 

 

 

When

 

the

 

jack

 

is

 

not

 

in

 

use,

 

make

 

sure

 

the

 

lifting

 

arm

 

is

 

fully

 

retracted

 

to

 

avoid

 

corrosion.

 

 

Replace

 

the

 

hydraulic

 

fluid

 

in

 

the

 

reservoir

 

at

 

least

 

once

 

a

 

year.

 

To

 

check

 

the

 

hydraulic

 

fluid

 

level,

 

lower

 

the

 

lifting

 

arm

 

completely.

 

 

The

 

hydraulic

 

fluid

 

level

 

should

 

be

 

just

 

below

 

the

 

filler

 

plug.

 

If

 

the

 

oil

 

is

 

too

 

low,

 

the

 

jack

 

will

 

not

 

raise

 

to

 

its

 

advertised

 

maximum

 

height.

 

Replenish

 

if

 

necessary,

 

and

 

reinstall

 

the

 

rubber

 

filler

 

plug.

 

Do

 

not

 

overfill

 

the

 

jack.

 

Excessive

 

hydraulic

 

oil

 

may

 

render

 

the

 

jack

 

inoperative.

 

 

Inspect

 

the

 

jack

 

before

 

each

 

use.

 

Take

 

corrective

 

action

 

or

 

remove

 

the

 

jack

 

from

 

service

 

if

 

any

 

of

 

the

 

following

 

problems

 

are

 

found:

 

 

A.

 

Cracked

 

or

 

damaged

 

frame

   

B.

 

Leaking

 

hydraulic

 

fluid

 

C.

 

Scored,

 

damaged

 

piston

 

rod

   

D.

 

Loose

 

hardware

 

E.

 

Modified

 

equipment

 

 

Keep

 

warning

 

labels

 

and

 

instructional

 

decals

 

clean

 

and

 

readable.

 

You
