Main components of the hand pump 4.
Functional description 5.
All LUKAS hand pumps of this series are two-speed, i.e. they have two operating speeds:
• A high speed in the low pressure range (LP) for fast extension of the cylinder or device
while unloaded
• A low speed in the high pressure range (HP) for controlled extension of the cylinder or
device while loaded
The switch from low pressure (LP) to high pressure (HP) is automatic at the factory setting
for changeover pressure (see chapter "Technical Data").
