safe usage instructions
1. It is the user's own risk and responsibility that the
pit has the correct dimensions and is an-chored to
the capacity demanded.
2. The pit jack should always be secured against
tilting (see "Assembly").
3. This is a lifting device only.
4. do not move or dolly load while on pit jack. T he
load must be supported immediately by other ap-
propriate means. (Order safety stand as optional)
5. do not overload. Overloading may cause damage
to or failure of pit jack.
6. Avoid decentral load.
7. Lift only on areas as specified by vehicle manufac-
turer.
8. It is recommended that wheels of vehicle be
chocked.
9. No person should work in, on, or get bodily under
a vehicle supported only by pit jack.
1 0. Only use one extension. (Optional).
1 1. T he safety valve being adjusted and sealed by
manufacturer shall not be additionally ad-justed.
1 2. Max. permissible pressure: 170 PsI - 12 bar.
1 3. Failure to heed these warnings may result in loss
of load, damage to pit jack, and/or failure resulting
in personal injury or property damage.
Assembly
First of all check the pit to have correct dimensions
and to be anchored for the capacity demanded. The
air hose (52) has been disassembled for transport and
replaced by a plug. Having assembled pit jack verti-
cally in pit take off the pump casing (44) and replace
plug with hose. A little oil may leak at gland during
this process. reassemble pump casing and connect
compressed air through bushing (22) (¼" Wrd pipe
thread), max. 170 psi - 12 bar.
To secure the pit jack against tilting mount bolts ad-
justed to the size of the craddle to spot-drilled holes
(thread M12) between screws (21) of trolley. Fix bolts
(L = height of profile + 40 mm) to pipe sections (L =
height of profile + 6 mm) and connect them in pairs
with a cross bar (flat iron 30 x 15 mm) equivalent to
outer width of cradle and secure them with bolts.
Use of Pit Jack
Lifting: Turn control valve (31) clockwise. Automatic
rapid lifting is activated until load has been reached.
Lowering: Open release handle (33) carefully by
turning it slowly counter-clockwise. For rapid lowering
turn simultaneously the control valve counter-clock-
wise.
Maintenance
like other pneumatic tools the pit jack is vulnerable to
water in the compressed air and it is recom-mended
always to use water separator with the compressor.
For extra security the pit jack is equipped with built-in
water separator and fog lubricator.
Daily: empty water separator by pushing button situ-
ated under glass (the water separator is automati-cally
emptied every time the air hose is removed).
Weekly: lubricate cylinder wall by lifting to maximum
position.
Monthly: Dismount glass and fill up the fog lubricator
with a thin oil (IsO vG 22). Adjust oil supply by turning
screw on top of the fog lubricator: Approximately 2
drops per min-max lift without load. lubricate all mo-
bile parts with a few drops of oil.
Yearly: Inspect pit jack for damage and wear and tear.
Refilling of oil: Refill with oil if the pit jack will not lift
completely with the engine running. Dismount the filling
plug (upper 26). Correct oil level is to lower edge of
hole for filling plug with the pit jack in lowest position.
Oil quantity: 4,0 l
Any good hydraulic oil of viscosity IsO vG15 can be
used.
Never use brake fluid!
Trouble Shooting
1. T he pit jack cannot lift to maximum height: Check
oil level (see "Maintenance").
2. The air engine runs slowly: Inadequate air supply
(min. 500 l/min) or pressure (min. 9 bar).
3. The pit jack cannot hold pressure: T he release
does not close tightly. Check initial tension of spring
(34): Tighten release handle (33) lightly and dis-
mount it. engage spring with hole on valve bracket
and place spring holder (56) on sprig. Place hole of
release handle for screw (20) approximately in front
of corresponding hole in valve spindle and push
release handle in place with spring holder engaged
with release handle; tighten spring max. ½ turn and
then mount screw.
Destruction:
When the pit jack after several years is worn and must
be dismantled, the oil must be drained off and le-gally
disposed of.
