Product Description - Enerpac PT Serie Hoja De Instrucciones

WARNING: Only use hydraulic cylinders in a coupled
system. Never use a cylinder with unconnected
couplers. If the
overloaded, components can fail catastrophically causing
severe personal injury.
WARNING: BE SURE SETUP IS STABLE BEFORE
LIFTING LOAD. Cylinders should be placed on a flat
surface that can support the load. Where applicable,
use a cylinder base for added stability. Do not weld or
otherwise modify the cylinder to attach a base or other support.
Avoid situations where loads are not directly centered
on the cylinder plunger. Off-center loads produce
considerable strain on cylinders and plungers. In
addition, the load may slip or fall, causing potentially
dangerous results.
Distribute the load evenly across the entire saddle
surface. Always use a saddle to protect the plunger.
IMPORTANT: Hydraulic equipment must only be
serviced by a qualified hydraulic technician. For repair
service, contact the Authorized ENERPAC Service
Center in your area. To protect your warranty, use only
ENERPAC oil.
WARNING: Immediately replace worn or damaged
parts by genuine ENERPAC parts. Standard grade
parts will break causing personal injury and property
damage. ENERPAC parts are designed to fit properly and
withstand high loads.
3.0 SAFETY INSTRUCTIONS SPECIFIC TO MONO-
STRAND STRESSING JACKS
1. DON'T stress any tendons which contain concrete slurry
inside the anchor cavity. Concrete in the anchor cavity will
prevent proper seating of the wedges. It is safer and less
expensive to clean out concrete slurry than to have to
detension, repair or replace tendons, or repair the jack.
2. DON'T use the jack when you can see that it does not seat
properly on the face of the anchor.

3. DON'T overstress tendons in order to achieve proper
elongation.
4. DON'T allow obstructions in the path of the jack extension.
5. DON'T continue stressing if you suspect that something is not
working properly.
6. DON'T detension with loose plates, spacing shims or piggy
backing.
7. DON'T stand immediate vicinity of the jack, or between the
jack and the pump during stressing or detensioning.
8. DON'T permit other workmen in the immediate area of the
jack or pump during stressing operations.
9. DON'T hammer or beat the jack or jack cylinders.
10. DON'T do anything if you are not sure - ask someone who
knows.
