Section 1: Overview and Safety
Hydraulic Impact Drill Overview
RRP designs and manufactures equipment primarily for the repair and new construction of rail and
railroad tie track maintenance.
Our product line focuses on rail fastening application/removal/adjustment equipment, other tie material
(OTM) reclamation, wood and concrete railway tie repair, and tie plate handling/distribution.
Hydraulic Impact Drill is a low pressure hydraulic impact drill MAG Series (Machined Aluminum, Gerotor)
designed for drilling holes and fastening hardware.
The body of this drill is made from aircraft grade extruded 6061-T6 Aluminum while the forged handle is
made from 7075-T6 aluminum. All internal porting is accomplished through CNC machining for precision,
reliability and increased repeatable performance.
The drill balances well in a gloved hand while the handle, grip and trigger have been ergonomically
designed for ease of operation. The drill incorporates proven gerotor motor for long life and greater
efficiency over gear type motors.

Always operate in a well-ventilated area and make sure that the air filters, air filter covers, and muffler
are in good condition.
Always keep the machine clean and free of debris. Operate the machine in a safe and responsible
manner. Exercise caution when fueling, working on or near rotating or moving components, hot
components and fuel systems. Be aware of potential fire hazards and prevent sparks, exhaust, etc., from
starting fires on the machine and/or work area.
Always comply with all instructions provided on any decals or placards installed on the machine and with
any relevant amplifying information provided in this manual or other general operating procedures.
Always shut disconnect the drill from the power source and make sure that all controls are in a safe
position and install all appropriate locking and safety devices before doing any of the following:
•Lubricating
•Adjusting
•Installing Tooling
•Making Repairs
•Performing Service
Tools are not insulated for use on or near energized conductors. Use of
these tools near energized conductors may lead to electrical shock, causing
severe injury or death.
Do not use these tools near energized conductors without adequately insulating
operator and surroundings.
Tool parts rotate at high speeds and can cause severe personal injury. Keep all
body parts away from moving parts of the tool when connected to a hydraulic
power source or during operation.
Operator must clear all bystanders from the work area when handling, starting,
and operating a tool to avoid injury to bystanders.
Do not over-reach while using a tool. Loss of balance can cause serious
personal injury or death. Move closer to work area and securely support yourself
and your work. Always keep proper footing and balance.

Hydraulic fluid is under pressure.
Always depressurize the hydraulic system before connecting or disconnecting a
tool to avoid serious injury from escaping fluid. If injury results from escaping
hydraulic fluid, seek immediate medical attention to avoid serious bodily injury.
Hot hydraulic fluid.
Exposure to hot hydraulic fluid can cause severe burns. Do NOT connect or
disconnect a tool while the hydraulic power source is running and/or the
hydraulic fluid is hot.
Never lock a tool trigger in the power ON position. A tool locked ON can lead
to serious injury or death

Hoses and Fittings
Always stop the hydraulic power source flow and depressurize the
system before connecting a tool. Failure to comply could result in
severe bodily injury.
Return (tank) hose connection should always be connected before
supply (pressure) hose connection to prevent pressure build-up
inside the tool which could result in severe bodily injury.
Hoses and fittings used with this tool must comply with SAE Standard J1273 (see Hose Selection)
recommended practice for Selection, installation and Maintenance of Hose and Hose Assemblies.
The recommended hose diameter for the supply line is 3/8 to 1/2 in.
Supply hoses must have a minimum working pressure rating of 2500lblin2 (17.5 Mpa). lt is recommended
that the hose diameter for the return line be equal to or greater than the supply line. This may help reduce
back pressure.
Connecting the Hoses
1. Stop the hydraulic power source.
2. Depressurize the system.
3. Allow system and hydraulic fluid to cool.
4. Remove dirt or debris from the couplers before connecting to a power source.
5. Securely connect the return (tank) hose from the power source (port T) to the tool (OUT port).
6. Securely connect the supply (pressure) hose from the power source (port T) to the tool (IN port).
Disconnecting the Hoses
Always stop the hydraulic power source flow and depressurize the
system before disconnecting a tool. Failure to comply could result
in severe bodily injury.
•Supply (pressure) hose connection should always be
disconnected from the tool before the return (tank) hose
connection to prevent pressure build-up inside the tool.
•Remove lines, fittings or components slowly to release any
trapped pressure.
•lf injury results from escaping hydraulic fluid, seek immediate
medical attention. Serious bodily injury may occur if proper
medical attention is not administered immediately.
1. Stop the hydraulic power source.
2. Depressurize the system.
3. Allow system and hydraulic fluid to cool.
4. Disconnect the supply (pressure) hose to the power source (port P) from the tool (IN port).
5. Disconnect the return (tank) hose to the hydraulic power source (port T) from the tool (OUT port).
6. To prevent contamination, always install dust caps over the hydraulic ports of the tool when
disconnected.
