Unpacking
Open shipping carton, which should contain one
toe jack and one 2-piece handle. Check for
shipping damage. Report any damage immediately
to your distributor and shipping agent. Do not
discard any shipping material until the toe jack is
set up and operating properly.
Operation
NOTE: Repeated operation near or at the rated
capacity may cause undue wear and shorten jack
life.
Figure 1 (5-ton model shown)
To raise the jack (see Figure 1):
1. Assemble the handle and place the end of the
handle over the release stem.
2. Turn the release stem clockwise completely to
close the valve. Do not over tighten.
3. Insert the handle into the handle socket.
4. Pump the handle to raise the load.
To lower the jack:
1. Place the end of the handle onto the release
stem and turn slowly counterclockwise to
open the valve.
2. Do not turn the release valve around more
than two complete revolutions.
Turning the release valve too
quickly will make the load fall rapidly, and may
lead to loss of load or damage to the jack.
Failure to heed may cause serious injury and/or
property damage.
When storing the jack, lower the ram completely
and wipe off any dirt, oil, or other contaminants.
Lubrication
1. Lubricate the pins (Figure 1) with a few drops
of machine tool oil monthly.
2. Lubricate the slide (Figure 2) with #2 lithium
base grease monthly.

To fill the reservoir with oil:
1. Completely lower the ram.
2. Remove the fill plug (Figure 1).
3. Fill the reservoir with hydraulic jack oil to the
bottom edge of the fill hole with the jack in the
upright position.
Make sure no contaminants
enter the cylinder when filling with oil. Never
use any oil other than hydraulic jack oil to fill
the cylinder.
4. Replace the fill plug.
5. Raise the ram to its full height and pump five
or six times after the ram has reached its full
height.
6. Push the ram down completely.
7. Push the fill plug sideways to let the trapped
air bleed out.
