1 Number One In The World For a Reason ® ® Holmatro Hydraulic Rescue Tool What You Need to Know to Maintain your Rescue Tool System © 4/2004 Holmatro

2 Number One In The World For a Reason ® ® Holmatro Session Objective Session Objective : 1.Review basic operation of hydraulic rescue tools. 2.Cover general maintenance, troubleshooting and inspection of rescue tools.

3 Number One In The World For a Reason ® ® Holmatro Table of Contents General Knowledge Quiz Basic Hydraulics –Pascal’s Law –Double Acting Cylinders –Tracing the Flow –Deadman’s Handle –Fluid Type

4 Number One In The World For a Reason ® ® Holmatro Table of Contents Cont’d. Hoses & Couplers –Coupling Procedures –Auto Lock Coupler –Pressure Relief Device –Hose No-No’s –Care and Maintenance of Hoses Pumps - The “Heart” of Your System –Starting Procedure –Operation Valve Function

5 Number One In The World For a Reason ® ® Holmatro Contents Cont’d. Tools –Personal Safety –Common Features Maintenance and Storage –Pumps –Tools –Hoses

6 Number One In The World For a Reason ® ® Holmatro General Knowledge Quiz What is the maximum operating pressure of your Holmatro system? 10,500 psi What type of fluid is used? Mineral based oil

7 Number One In The World For a Reason ® ® Holmatro General Knowledge Quiz True or False: two tools can be powered at the SAME time by your pump. True. The tools operate simultaneously, completely independent of each other, sharing only the oil in the reservoir. True or False?: When running, the pump is always moving fluid. True. When the motor is spinning, the pump is pumping. The oil will be circulating to the tool and back. With no tool attached to the pump the oil circulates back to the tank.

8 Number One In The World For a Reason ® ® Holmatro General Knowledge Quiz How do you relieve the pressure in a hot hose? Use the pressure relief device which is hanging from the pump.

9 Number One In The World For a Reason ® ® Holmatro What is Hydraulics? A means of transmitting power by pushing on a confined liquid.

10 Number One In The World For a Reason ® ® Holmatro Pascal’s Principal: P x A=F Pressure times Area Equals Force Pascal’s Law: Pressure applied on a confined fluid is transmitted undiminished in all directions, and acts with equal force on equal areas, and at right angles to them

11 Number One In The World For a Reason ® ® Holmatro This works because: Mineral Oil Does Not Compress The System is Filled –Hoses and tools are filled with oil –There is no air in the system The System is Sealed The Pressure is the same in all areas which are pressurized

12 Number One In The World For a Reason ® ® Holmatro Deadman’s Handle Operation Same on all tools Automatically returns to neutral when released Clockwise (CW) always opens Counter-clockwise (CCW) always closes

13 Number One In The World For a Reason ® ® Holmatro Deadman’s Handle Operation When at rest the handle is in the neutral position. This sends the oil in a U-turn back to the pump. No motion of tool. Rotating the handle either CW or CCW directs oil to either the bottom or the top of the piston, causing the tool to open or close.

14 Number One In The World For a Reason ® ® Holmatro Couplers - Care Keep Couplers Clean!! NO DIRT Keep Dust Caps On Clean With WD40 or Silicone

15 Number One In The World For a Reason ® ® Holmatro Mineral Oil Hydraulic Fluid Non-toxic Non-caustic SAFE! Use approved equivalents only Change at LEAST once per year to remove contaminants

16 Number One In The World For a Reason ® ® Holmatro System Components

17 Number One In The World For a Reason ® ® Holmatro SR20PC2 Spider 3-stage Pump Check Fluid Levels Operating Controls

18 Number One In The World For a Reason ® ® Holmatro Pumps –Operation SR20 Spider What is a 3-stage pump? Stage 1 For opening and closing with no resistance psi (tool runs fast) Stage 2 (new) For average cuts and pushes some of the speed of 1 st stage and some of the power of 3 rd stage 1,500 – 5,000psi Stage 3 For harder cuts and pushes slower tool but lots of power 5,000 – 10,500psi

19 Number One In The World For a Reason ® ® Holmatro Pumps - Operations SR20 Duo Check level of mineral oil -should be between marks (on side of tank) Use only approved fluid

20 Number One In The World For a Reason ® ® Holmatro Pumps – Operations SR20 Honda Duo Starting the pump –Choke On/Off

21 Number One In The World For a Reason ® ® Holmatro Operation Controls – SR20 Spider No dump valves on Pump! Change tools Without having to dump pressure.

22 Number One In The World For a Reason ® ® Holmatro Pumps - Operation SR20 Honda Duo Fuel Cap Carbon filled cap, if pump is tipped over carbon in cap will absorb fuel and may harden and not allow air into tank. This can cause a vapor lock. Cap may need to be replaced.

23 Number One In The World For a Reason ® ® Holmatro Rescue Tools Common Features Personal Safety

24 Number One In The World For a Reason ® ® Holmatro Common Features Cutters & Spreaders Light Balanced at Carry Handle 360° Access to Operation Handle I - bolt technology Integral Safety Relief Compact LED lights

25 Number One In The World For a Reason ® ® Holmatro Common Features Cutters & Spreaders LED Lights on Carry Handles On/Off Switch on back of carry handle AA battery remove two screws to change If lights will not turn off batteries need replacing

26 Number One In The World For a Reason ® ® Holmatro Common Features Telescopic Rams Grip heads rotate Cross design on grip head Extremely powerful

27 Number One In The World For a Reason ® ® Holmatro Pressure Relief Device Heat Causes Oil Expansion Expansion makes coupling impossible Pressure Relief Device is Used to Allow Coupling.

28 Number One In The World For a Reason ® ® Holmatro 4050NCT Cutter 7 1/8 Blade opening 208,000lbs cutting force 43lbs NCT blades ( Pulls material into cutting notch)

40 Number One In The World For a Reason ® ® Holmatro Maintenance and Storage Pumps Shut off pump with either throttle control or stop switch Put pump in ready position according to your local SOPs. Check fuel level. Inspect pump for damage - Frame, reservoir, PRD, couplers, etc. Clean couplers and dust caps before installing. Recommend using Seafoam or other gas stabilizer in fuel.

41 Number One In The World For a Reason ® ® Holmatro Maintenance and Storage Hoses Inspect hoses for any kind of damage: kinks, cuts, abrasions, etc. If the hose came in contact with any foreign fluids, such as brake fluid, transmission fluid, oil, etc. clean using mild soap and water as soon as possible. To prolong the life of your hose, minimize exposure to contaminants. Ensure that bend restrictors are in place and couplers are not damaged. Coil hose. Clean couplers and dust caps before installing. Immediately remove any damaged hose from serviceImmediately remove any damaged hose from service
