BEFORE USE
1. Inspect crane before each use. Do not use if bent,
broken or cracked components are noted. Ensure
that casters/wheels and boom move freely. Check
for and tighten any loose assemblies.
2. Verify that the product and the application are
compatible, if in doubt call Atd Tools Technical
Service (636)272-9050.
3. Before using this product, read the owner's manual
completely and familiarize yourself thoroughly with
the product and the hazards associated with its
improper use.
3. Open the release valve by turning the release valve
lever
counter-clockwise (no more than 1/2 full turn).
4. With ram fully lowered, remove oil ller plug and pump
handle 6 to 8 full strokes. This will help release any
trapped air within the reservoir. Ensure the oil level is
just below the oil ller hole. Reinstall the oil ller plug.
Close release valve by turning it clockwise rmly.
5. Check to ensure that crane rolls freely, that the pump
and release valve operate smoothly. Raise and lower
the unloaded crane throughout the lifting range be-
fore putting into service.
6. Replace worn or damaged parts and assemblies
with Factory Authorized Replacement Parts only.
