a torque wrench, tighten each bolt to
between 70 and 80 ft.-Ibs.
IMPORTANT: The swing-bolts must be
kept very tight to prevent damaging wear
to the dog clutch coupling, alignment pin

OPERATING INSTRUCTIONS
To help avoid personal injury or
damage to equipment, read the attach-
ment's Owner's Manual supplied with
each attachment before installing or
operating an attachment. Please read
all control, operation and safety
instructions.
The following are operating instructions
specifically for the PTOPower Unit. Read
the separate Owner's Manual supplied
with eachattachment before attempting
to assemble, attach, transport or operate
the attachment. If needed,pleasecontact
us for a replacement manual. See the
back cover for customer support
information.
To help avoid personal injury, always
disengage the Tines/PTO Clutch Lever
beforetowing any attachment.
Some attachments have a drive shaft or a
hydraulic pump that is powered by the
engine on the PTO Power Unit. These
units are called Stationary Attachments,
since they remain in one location when
operating. Attachments can be towed to a
work site with the PTOPower Unit as
described in OperatingNon-Powered
Attachments. Other attachments are
pulled or towed behind the PTOPower
Unit. These attachments are called Non-
PoweredAttachments.
Setting Up Stationary Attachments
To help avoid personal injury, never
allow people to ride on any PTO Power
Unit or attachment.
1. Move the Tines/PTOClutch Lever to
DISENGAGE.
2. Move Wheel Speed Lever (Figure4-22)
to FREEWHEEL, then block all wheels
(Figure 4-29) to prevent the equipment
from rolling.
