4.1 Truck Requirements

Long Reach attachments have been designed to oper-

ate within specific limits. Operating pressures above the

stipulated maximum may cause structural damage to the

attachment and may result in loss of warranty. Hydraulic

flow less than the recommended rates, or the use of small

I.D. hoses may reduce operating speed. Higher flow can

result in excessive heat buildup, erratic operation and

damage to the truck/attachment hydraulic system.

Notice

The dealer and/or the user are responsible

for installing any valving required to meet

the recommended hydraulic pressures and

flow. The required valving can be furnished

by the dealer, the truck factory or Long

Reach. The model description, found on your

shipped invoice, will state the following truck

requirements: flow (gpm), psi, and minimum

truck carriage width.

4.2 Hydraulics

1. The truck hydraulic system must supply to the at-

tachment hydraulic oil that meets the specifications

required to operate the attachment properly.

2. When the truck hydraulic system pressures exceed

this maximum, a relief valve is recommended in the

attachment auxiliary system of the truck or on the

attachment. Consult the truck factory and/or Long

Reach for guidance.

4.3 Attachment Installation

1. Customer is to supply the mounting plate for the

attachment.

2. The attachment is bolted to the mounting plate using

16 supplied 3/4 UNC X 3 hex head capscrews that

have been been treated with high strength/high temp

Loctite Threadlocker 272 (Red) and 16 hard flat wash-

ers. Torque the bolts to 278 ft/lbs.
