Description

The Greenlee Utility HB10 Dynapress®Hydraulic

Booster is a piston-type accessory intended to allow the

use of a high pressure/low ow tool with a low pressure/

high ow hydraulic power source. Compatible with

either Open-Center or Closed-Center hydraulic systems,

the unit takes a hydraulic input of 69 to 152 bar (1000to

2200 psi) and produces a stable output of 700 bar

(10,000 psi).

The HB10 can be installed in existing two-hose type

hydraulic systems, and does not require a third hydrau-

lic line or separate reservoir. The compact and light-

weight design allows the unit to be easily carried and

used on the ground or in an aerial lift basket. Actuating

the high-pressure circuit of the Dynapress requires a

remote control valve, purchased separately. The instruc-

tions and illustrations in this manual reect using the

HB10 with either of the following Greenlee Utility remote

control valves:

PVA0021A (Single-Acting Control Valve)

PVA0022A (Double-Acting Control Valve)

The terms “unit” and “booster,” when used in this

manual, refer to the HB10. The term “tool” refers to the

device (cable cutter, crimping tool, etc) that is powered

by the HB10.
