30" SHARK Operations and Maintenance
The 30" SHARK is a horizontal shaft type, directly driven, rotary forestry mulching
attachment designed for use in conjunction with boom-equipped carriers. The unit is
comprised of a cutting frame and cutting drum driven by a hydraulic motor equipped with
protective valves and associated hydraulic fittings and conductors. The unit is fitted with
guarding to limit access to the cutting drum and designed to limit flying debris that may be
ejected during clearing operations.
The unit is designed for use in the safe and efficient reduction (to chips/mulch) of all types of
vegetation up to diameter of 180mm and is to be used only in applications where personnel,
property and roadways are greater than 100 meters from where the mulching equipment is
being operated.
Audience
This user guide is written for operators who use and maintain the Torrent 30” SHARK
Forestry Mulching Attachment during vegetation clearing activities.
Precautions
Failure to follow and respect the following WARNINGS can result in damage to the mulcher,
the carrier, other property or injury or death of operation personnel or pedestrians. This unit
must not be used within 100 meters of objects, other machinery, livestock, pedestrians, or
personnel (other than the operator)
WARNING: This machine must be operated only by qualified equipment operators with
thorough knowledge and understanding of the contents of this manual. RWI accepts no
responsibility for damage or injury resulting from inappropriate or misuse of its products.
WARNING: Before starting the supply of hydraulic oil to the mulcher the operator must
verify that equipment, personnel, property, and roadways are greater than 100 meters from
where the mulching equipment is being operated. As well, the operator must be inside the
operator’s compartment of the machine with the doors and windows closed.
WARNING: The 30” SHARK must not be approached by persons (including the operator) or
by other equipment while the cutting drum is turning. Because of the risk of entanglement
or debris that may be ejected from the unit, the 30” SHARK must be in a ZERO ENERGY
STATE (that is, the drum is stationary, the cutting frame is squarely on the ground and
excavator engine is shut down) before being approached for inspection or maintenance.
WARNING: The 30” SHARK must not be used in water.

30" SHARK

WARNING: Because of the nature of the hydraulic motor protective valving supplied on the
mulching unit, the cutting drum will continue to rotate after the unit is shut down until all
inertial energy is expended from the cutting drum. Always allow the unit at least two
minutes to “run-down” after the carrier has been shut down before approaching the unit for
any reason.
WARNING: This machine must be installed according to the product technical specifications
contained herein by qualified technical personnel only. RWI Ltd. accepts no responsibility for
damage or injury resulting from inadequate or improper installation of its products.
WARNING: When servicing cutters, the cutting drum must be mechanically prevented from
turning (that is, wedged or blocked) to minimize the risk of injury to the maintainer.
WARNING: The 30” SHARK is manufactured from metal components and, as such, is a highly
efficient electrical conductor. Extreme caution must be used when working around electric
power transmission lines whether above or belowground!
WARNING: This machine must be installed and used in observance of all laws, rules and
regulations as laid out by local regulatory bodies in the country/region in which it is being
used.

Operation
Clearing operations should be carried out only by a competent equipment operator familiar with
the safe operation of the 30” SHARK when installed to the applicable carrier. The operator must
understand the contents of this manual.
Before starting the supply of hydraulic oil to the mulcher the operator must verify that
equipment, personnel, property, livestock and roadways are greater than 100 meters from
where the mulching equipment is being operated. The operator must always remain inside the
operator’s compartment while the mulcher drum is turning.
For lighter growth, such as bush and smaller trees up to 2" (50mm), material is most efficiently
reduced by approaching the work from the left, such that material is introduced into the “feed
side” or left side of the mulcher. This allows the cutting drum assembly to pull the material in to
be reduced and then ejected downward from the discharge side of the mulcher.
Figure 1. Discharge Side

30" SHARK

Vegetation 2" (50 mm) and larger in diameter, often require that the top be cut off and mulched
separately on the ground. In addition, with respect to larger growth it is faster and more efficient to
chip/mulch as much of the tree as possible while it is standing (still on the stump). For efficient
mulching of larger trees, the steps to remember are as follows:
1. Reach as high as safely possible (that is, boom highest position with mulching head
horizontal) toward the right side of the tree.
2. Using the left or “discharge” side of the mulching drum, slowly cut into the right portion of
the treetop being careful not to cut the top off completely.
3. As the top weakens, apply increasing left swing pressure until the combination of cutting
and swing forces cause the top to fall .
4. Using slight down pressure, trees 3” (75mm) and smaller may me reduced using the guard
to direct the stem into cutting drum continuing to mulch the stem down to grade.
5. Swinging from left to right introduce any material on ground into the feed side, to be
reduced and ejected from the unit

Preventive Maintenance Instructions
This section provides the information necessary to ensure safe and effective maintenance of
the 30” SHARK forestry mulching attachment. Periodic checks and lubrication requirements
are described in detail.
DAILY
Check Hydraulic Conductors for Leaks or Damage
The hydraulic hose assemblies connecting the mulching unit to the boom of the carrier are
exposed to impact and abrasion as a normal course of operation.
Hydraulic hoses and fittings must be checked regularly in order to avoid any soil
contamination due to leakage of hydraulic fluid and to maintain the proper level of oil in the
hydraulic system. Restrictions in the hydraulic conductors can adversely affect the
performance of the mulcher and, in some cases, cause damage to the hydraulic motor.

Inspect Cutters for Excessive Wear or Breakage
As cutters wear, they become less efficient. Rotate cutters as required.
To rotate, a cutter perform the following steps:
1. Remove cutter fastener and lock washer.
2. Turn 90 degrees, or as required, to expose a new cutting edge. –if no new edges
remain, replace the cutter with a new one.
3. Torque to 75 Nm.
Do not use an impact wrench to tighten the cutters. Remove/replace a cutter as follows:
1. Remove cutter bolt and lock washer.
2. Remove cutter from tool holder.
3. Replace exhausted cutter with a new one.
4. Reinstall cutter bolt and lock washer and torque to 55 ft-lb (75 Nm).

30" SHARK
Owner’s Manual

WEEKLY –Every 50 Hours of Operation
Inspect Tool Holders for Excessive Wear or Damage
In cases of severe damage to cutters involving loss of the entire cutting head, the tool holder
tool face may be exposed to impact with potential for damage to the machined surface. Any
damage to the machined surface must be corrected. In cases of severe damage, a new tool
holder must be installed.
Check Bearings for Excessive Radial clearance or Endplay
With the unit squarely on the ground, or other flat solid surface, and with the carrier in a
ZERO ENERGY STATE, slide a pry bar under the drum ting. Check for excessive radial
clearance. Readily visible movement while moving the pry bar up and down, may indicate
worn or damaged bearings.
Excessive endplay may be detected by placing a pry bar between the cutting frame and
either end of the cutting drum. A small amount of end-play (approximately 1/16” (1.5mm) is
built into the bearing. If total axial play (in excess of 1/16”) is detected, bearings may have
be replaced and further inspection is required.
Verify Cutter Fastener Torque
Using a torque wrench, check that all cutter bolts are tightened to a value of 55 ft-lb (75Nm).
Inspect Hydraulic Motor, Valving and Hydraulic Hose Connections for Leaks
Place the unit squarely on the ground, or other flat solid surface, and ensure that the carrier
is in a ZERO ENERGY STATE. Allow the unit to cool to ambient temperature. Remove the
drive end cover and inspect the hydraulic motor and anti-cavitation valve assembly hose
connections for leaks or seepage of hydraulic oil and correct as necessary.

30" SHARK Installation
Installation of the 30” SHARK must be carried out by a factory trained technician or with
extensive experience in hydraulic fluid power systems and components. The technician must
possess knowledge and/or documentation specific to the excavator brand, model and model
year to which the unit is to be installed and should commence installation of the 30” SHARK
only after having read and understood the contents of this manual.
Warning: All installation and any other maintenance or mechanical procedures
to be carried out on the 30” SHARK must be performed with the unit resting
squarely on the ground or other flat solid surface, and with the carrier in a ZERO
ENERGY STATE.
The 30” SHARK is a hydraulically driven, rotary mulching attachment driven by a fixed
displacement axial piston hydraulic motor rated for a maximum continuous operating
pressure of 5000 psi (345 bar). The hydraulic motor is fitted with case overpressure
protection and anti-cavitation valves.
The 30” SHARK cutting drum shaft is supported at either end by flanged cartridge roller

Hydraulic Connections
Pressure Oil
The circuit relief setting of the pressure oil supply should be no less than 3000 psi (207 bar)
to maximum of 5000 psi (345 bar). Motor torque is directly proportional to the value of the
supplied pressure and so higher supplied pressure translates into increased performance
and reduced time required to bring the rotor from dead stop to full speed. The minimum
recommended pressure supply line size is ¾” (19mm) inside diameter and capable of
withstanding pressure established by the circuit relief setting.
Main Return Oil
Main return oil may pass back to tank through the directional control valve section from
which the pressure oil is supplied. A more efficient configuration is to have the return oil
circumvent the control valve directly back to tank thereby avoiding back pressure and heat
generated due to throttling losses encountered in the directional control valve.
