2.2 Tool Preparations

The Spike Puller is ready for use afterunpacking and no special preparation isrequired.

If the tool is used in cold weather,preheat the hydraulic fluid by runningpower source at low engine speed. Fluidtemperature should be at or above 50°F/10° C (400-ssu/82 centistroke) beforeuse, when using recommended fluids.Using too thick of fluid may result intool damage.

2.3 Testing

WARNING: NEVER STICKFOREIGN OBJECTS, FINGERS, OROTHER EXTRMIIES INTOMOVING MECHANISMS.FAILURE TO FOLLOW THESEINSTRUCTIONS MAY LEAD TOSEVERE PERSONAL INJURY ORTOOL DAMAGE.

Before operating the spike puller it isimportant to inspect the trigger linkagemechanism for obstructions. Make sureall kits and components are securelymounted and tight. Follow all safetyprecautions when inspecting tool.

1. Connect the tool to the power sourcefollow the procedures in section 2.6 ofthis manual.

2. Verify that the pressure and returnhoses are connected properly to the tooland hydraulic power source ports.

3. The hydraulic power source reservoirmust be filled to full level with hydraulicfluid.

4. After verifying the above, start thepower source flow. All power sourceshut-off devices must be engaged oropened (clutch engaged, separateON/OFF valves open, etc.)

5. Check the tool to see if it operates.

NOTE: If the tool does not operate, itwill be necessary to determine where theproblem exists (i.e., in the tool, hoses, orhydraulic power source).

DETERMINING THE PROBLEMAREA

1. Stop the power source. Depressurizethe system and allow to cool.Disconnect the existing tool from thehoses and power source. See action onhose connections in this manual forproper procedures.

2. Connect a known, properly operatingtool to the hoses and power source. Seethe tool’s operator manual for the correcthook-up procedure. Start the powersource flow.

If the known, properly operating tooloperates, the problem is in thedisconnected tool. See thetroubleshooting charts in this operator’smanual.

If the known, properly operating tooldoes not operate, the problem is likely to

be in the hoses or the power source.Proceed to Step 3

3. Stop the power source flow.Disconnect the existing hoses from theknown, properly operating tool andpower source. See the tool’s operatormanual for the correct disconnectprocedure.

4. Connect a different set of hoses to theknown, properly operating tool andpower source. Start the power sourceflow.

A. If the known, properly operatingtool operates with the different setof hoses, the problem is in thedisconnected hoses.

B. If the known, properly operatingtool does not operate, the problemis in the power source. See yourpower source operator’s manualfor troubleshooting.

If, after following all steps in theTroubleshooting section, it has beendetermined that the problem lies with thetool, proceed to the TroubleshootingGuide. Use of the TroubleshootingGuide will help you identify anddetermine the cause of the problem.

NOTE: It is not recommended that theend-user attempt to perform repairs, asspecial tools and procedures arerequired. We cannot be responsible forthe heat generated through anycombination of pump inefficiencies, oilbypassing over relief valves, pre-existingflow controls, or unusual restrictions inthe system. Where these and otherpossible inefficiencies exist,substantially larger reservoirs and/orcoolers may be required.

Should you have any problems orquestions with your Hydraulic Tooling,please do not hesitate to contactCustomer & Technical ServiceDepartment at PortaCo, Inc.

2.4 Hose Requirements

It is not often necessary or advisable touse long hoses. All hoses must have anoil resistant inner surface and anabrasion resistant outer surface. Eachhose must have male pipe ends for mostapplication. Longer hoses can be usedwhen necessary, but can affect theoperation of the engine due to resistancein the hose. If small diameter or longhoses are used, or if restrictive fittingsare connected to the supply and returnports, the pressure required to push thefluid through the system and back to thetank will be higher. This will reducetool power.

*Important – Oil should always flowfrom the male coupler through thefemale coupler.

NOTE: The pressure increase inuncoupled hoses left in the sun maymake them difficult to connect. When

possible after use, connect the free endsof the operating hoses together.

HOSE TYPES

Hydraulic hose types authorized for useby PortaCo, Inc. is as follows:1. Labeled and certified non-conductive2. Wire braided (conductive)3. Fabric braided (not certified or

labeled non-conductive)

Hose 1: Listed above is the only hoseauthorized for use nearelectrical conductors.Hoses 2 and 3: Listed above areconductive and must never be used nearelectrical conductors.
