Hyster and Yale IFAK Diagnostic Tool

Ifak for Nacco forklifts. Aftermarket parts by Intella LiftpartsYou’ve watched the technician from the Hyster or Yale dealership using his laptop computer and the Ifak cable to diagnose and program your forklift. Pretty cool, right?

So how does this help him repair your forklift?

The software reads the on-board diagnostics built into your forklift. It contains a database of all of the possible diagnostics codes in the system and the associated troubleshooting guides. The tools included allow the technician to test individual components right from the computer screen without opening his toolbox. He can also make adjustments to your forklift’s transmission, speed control, operator access, impact monitors and many others. He can look at temperatures and operation history and current status. All of this helps your technician to diagnose and repair your forklift in short order.

Now you want to know where you can get the software and IFAK interface cable.

Sorry, they’re not available for sale anywhere we’ve found.  Even if you could purchase one, you wouldn’t have access to the Hyster/Yale website that the dealers use with their laptops.

Ifak for Hyster Yale forklifts. Aftermarket parts by Intella Liftparts

Nacco (the parent company for Hyster and Yale) will only allow access to their software to fully trained and certified technicians that work for their dealerships. It is easy to explain when you understand what is at stake.

The adjustments available to the technician are very complicated and take a great deal of training to understand how to correctly calibrate and adjust your forklift. There are also some options available that are activated through software and must be purchased through your dealer. Nacco technicians are required to take hundreds of hours of factory training to become certified with their software. If an untrained person were to make certain adjustments it could cause an unsafe condition.

The liability for the dealer and the manufacturer would be enormous.

All is not lost.

The forklifts built today give the technician or customer access to much of these diagnostics tools through a menu system on the dash. You can access most of the diagnostics codes and make limited adjustments right from the dash display.   Often many dealers technicians don’t even use the IFAK cable–they simply look at the code displayed on the dash.

It is important to remember that many mechanical problems can be diagnosed and repaired in the same way as in the past. Forklifts are still basic machines that have become safer and more efficient thanks to technology.

Inspecting Impco Systems for High CO Levels

Step 1: Squeeze Hose

Use a needle-nose pliers to pinch the vacuum hose on the VFF-30. If the RPM speed changes, the o-ring seal is bad. If after disconnecting the hose the engine doesn’t die or the o-ring is bad, the Impco VFF-30 needs to be replaced or rebuilt. You can also test this using carbon monoxide readings.

*If you have an electric lockoff in your lift truck, you will also have a vacuum safety or an oil pressure switch. It is against regulations for these to be disconnected (see NFPA Pamphlet 58).

Step 2: Prime

Push the primer button while the engine is running on the Model J vaporizer-regulator. IMPCO no longer manufacturers a model J with a primer button.  However, primer buttons are available on Impco model J generic units which we offer.  The engine should stall or completely shut off while pushing the button and start back up to idle as soon as you release. If this doesn’t happen or pushing the button causes the engine to speed up, adjustments are needed with the air-fuel mixture in the mixer.  To watch how a Impco model J is rebuilt, check out this video here.  A video on how to rebuild an Impco VFF30 can be found here.

Turn the idle mixture screw (on the mixer) counterclockwise as far as possible. The emissions reading should decrease in carbon monoxide.

Take out the air filter and inspect it. Replace the filter if there is an increase or decrease in emissions after the air filter is removed.

Step 5: Mixer

If you haven’t had any problems with anything in steps 1-4 and CO levels are still too high, the mixer must be replaced. Usually, you can replace your Impco Model 50 carburetor/mixer with a new Impco Model 100 or 125 with minimal adaptations. If this is not the case for you, go with a Model 55.

Step 6: Air Valve

There are 4 screws holding the Impco Model CA100/125 mixer cover that need to be removed in order to check out the air valve. (It should be part AV1-14-4; if not, replace with the correct part.) Make sure the metering cone is clean on the inside and there are no signs of wear. If you see marks implying the valve is rubbing, either sand the guide gently or replace the air valve. A lean air shim or 2 may be installed at this point if the fuel mixture still isn’t right.  Install the first shim on the metering cone lip and check the emission levels; if only a minor improvement, add the second shim.

*Clean the air valve with a solvent solution. Do not wash the diaphragm or use an abrasive cleaner on any parts. Make sure the gas valve cone is tight in the body housing.

Step 7: Power Mixture Setting

Emissions should be at an acceptable level when the truck is idling. Set the power mixture and load the mast by tilting completely back or forward. If you have a rich condition based on the exhaust analyzer, turn the power valve, or gate valve as its also known, to the “L” position.

Forklift backup cameras @ ProMat 2015

Day four!  Final day.  It could be argued that ProMat could simply be a 3 day show.  The fourth and final day lacks the energy of the first 2 days as exhibitors are worn out, and traffic in general is significantly lighter.  As an exhibitor, we tend to walk the show on Thursday simply because the traffic at our own booth is very light.

ProMat 2015 Goals

We had the following goals at ProMat 2015:  first, introduce our new products lines: forklift backup cameras, ATIB Chargers, BlueSpot(R) Safety light, and LED work lights.  Our second goal was to find new customers.  On both points we succeeded in a big way.  ProMat is the largest material handling show of its kind in North America.  One could argue that there are a number of exhibitors which have nothing to do with forklifts, and that’s true.  However, the crowd is so large it dwarfs any other event out there.  Over 40,000 end users, over 3,000 forklift dealers…show me another event where 3,000 forklift dealer personnel are attending–yep, there isn’t one.

Forklift Backup Camera Systems

A big hit at the show was our new product line of forklift backup cameras.  We entered this market about a year ago; our product line includes wired and wireless forklift camera systems, along with a variety of monitors.  They help operators see what’s behind them before they back up.

Wired forklift camera systems start at $499.00 / wireless forklift camera systems start at $599.00
