What Tools Can Be Powered - Husqvarna PP 418 Manual De Instrucciones

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:
Flow Requirement:
Maximum Pressure:
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.
Examples of Husqvarna hydraulic tools that can be used
with the PP 418 without any modifi cations:
• Hand Saw
• Ring Saws
• Core Drill
• Wall Saw
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.

HYDRAULIC HOSES AND
COUPLERS
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 recom-
mend 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" compa-
tible quick couplers.
CAUTION
The hydraulic hoses and fi ttings shall have a mi-
nimum pressure rating of 140 bar (2000 psi) with a
safety factor of 4 to 1.
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 oppo-
site end. Never use two fi ttings of the same gender
on the same hose.
CAUTION
The hydraulic oil and therefore the hoses and hy-
draulic 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)
