Removal
1.
Make sure axial movement of clamp collars - necessary for release of connection - is not resricted.
2.
Relax all locking screws by at least 2 turns and transfer locking screws into all push-off threads
provided in clamp collar item "1" and center collar item "3" as illustrated in Figure 2.
3.
Release connection by progressively tightening all push-off screws in diametrically sequence except
for screws adjacent to slit in clamp collar item "1", which should be tightened one after the other.
General Instructions
1. The brushcutter requires a constant flow of hydraulic oil that will not be reduced when another machine
function is used simultaneously.
2. Use a "Motor spool" type of control valve. If not possible, a system of recirculating check valves must be
used. Circulating system and crossover relief for drive motor protection are provided with the cutter.
3. Line Sizes: All pressure lines are to be minimum 1" diameter. All return lines, 1 1/4" tubing (except when
dual rotation is used-both lines must be high pressure. Flows below 30 GPM may use smaller line sizes).
Confirm line size with each application.
High pressure machines use a motor capable of operating at 3500 p.s.i. with a correspondingly lower flow
rate.
4. The shaft speed must not - UNDER ANY CIRCUMSTANCES - exceed 1800 RPM.
5. Secure all wear parts as per factory original installation. (Follwing servicing, sharpening, etc.)
