WHAT TOOLS CAN BE POWERED
The PP 418 power pack is equipped with an adjustable fl ow
hydraulic pump which produces hydraulic power more
effi ciently than a more commonly used fi xed displacement
gear pump.
The PP 418 power pack is suited to power any hydraulic tool
with the following specifi cations;
Hydraulic valve: “Open Center”
Flow Requirement: 20, 30 or 40 l/min
(5, 8 or 10 gal/min)
Maximum Pressure: 140 bar (2000 psi) or higher
The PP 418 includes a 7.5 m (25 ft) long hose set in a 1/2”
(12.7 mm) inside diameter. You can attach ONE additional
1/2” hose of up to 10 m (33 ft) (total of 18-20 meters / 60-65 ft).
If you require a longer hose for your application we
recommend the following:
Maximum hose extension - up to 40 m (130 feet) total distance:
- Use the 7.5 m (25 feet) of hose included with the power pack.
- Make two 16 m (53 ft) extension hoses in a minimum of 5/8”
(16 mm) hose diameter.
One 32 m (100 ft) length can also be used - however it is more
bulky to handle.
We strongly recommend using HTMA “Flat Face” compatible
quick couplers.
HYDRAULIC HOSES AND COUPLERS
Examples of Husqvarna hydraulic tools that can be used with
the PP 418 without any modifi cations:
Hand Saw K2500
Ring Saws K3500, K3600
Core Drill DM406H
Wall Saw WS325
Other popular tools are:
Hydraulic Chain Saw
Hydraulic Water Pump
Hydraulic Breaker
If you are unsure of the compatibility of any tool - please
consult the tool manufacturer or
Husqvarna Construction Products.
NOTICE:
The direction of fl ow through the system is always; male fi tting
into the female fi tting. This means that any extension hoses
should be made up the same way. If you have a male fi tting in
one end of a hose you should always have a female fi tting in
the opposite end. Never use two fi ttings of the same gender
on the same hose.
CAUTION
The hydraulic oil and therefore the hoses and
hydraulic couplers can get scalding hot during normal
operation.
A hydraulic coupler at a temperature of 50°C (120°F) will be
perceived as HOT to the touch. It is normal that the power
pack oil might become as hot as 60°C (145°F) if operated on
a very hot day with ambient temperatures exceeding 40°C
(104°F).
For reference - a car engine typically operates at 90°C (195°F)
CAUTION
The hydraulic hoses and fi ttings shall have a
minimum pressure rating of 140 bar (2000 psi) with a
safety factor of 4 to 1.

CAUTION
If a tool requires 20 lpm/5 gpm of fl ow - it SHALL NOT
be operated with a higher setting – such as 8 or 10
gal/min. This can cause severe damage to the tool or
even personal injury.
Always consult the manufacturer of a tool before
hooking it up to the power pack.
