Using The Cardlock

Using Cornerstone Co-op Cardlocks isn't much different from any self-service gas pump. The only major difference is that you'll have to enter your cardlock PIN before fuelling. The guide below will take you through each step of the process:

Key in account type and press ENTER


Begin fueling using the pump indicated


Do not leave pump or nozzle unattended

Begin fueling your vehicle within one minute.

After fueling, please turn pump (and satellite if applicable) to OFF position to stop the transaction. Hang up hoses. If desired, proceed to activate the Ticket Receipt Printer. Follow the Receipt printer instructions carefully.


Insert the card into the slot

Press "YES"

Take receipt after printing is complete.

The cardlock equipment at some of the sites in the Co-op and Tempo® network is being upgraded to accept a mag stripe cardlock card in addition to the currently used punched card. Sites that have been updated with this equipment will have 2 slots to insert cards at the card readers. Please use the appropriate slot for the punched card or the mag stripe card that you have been issued to use. Note that the Dual Card Reader sites (which accept punched or mag stripe cardlock cards) have slightly different instructions for keying. Watch the prompts and enter the appropriate information.


Problem:Pump requested will not operate. Cardreader states “PUMPHANDLE? RE-ENTER”.

Solution:You may have turned the pump handle on before you requested the pump, or handle was left on from the previous transaction. Turn off the pump and start the procedure again. Commence fueling.

Problem:Pump has been selected and turned on, but no fuel is delivered from the nozzle when squeezed.

Solution 1:If the pump is equipped with a twin hose (large and small nozzle), be sure the 3-port 2-way valve on the pump is turned to select the hose and nozzle you wish to use. Commence fueling.

Solution 2:If the pump is equipped with a satellite dispenser, be sure your main pump is turned on. If the 3 port 2 way valve is on the pump, be sure you have selected the correct hose, if necessary, to direct product flow. Commence fueling.

Solution 3:If the satellite is switched on, the main hose will not work. Turn satellite off, main hose will now work. Commence fueling.

Problem:Pump is pumping and meter is running but no product is dispensed.

Solution:Stop fueling and contact us with details as soon as possible.

Problem:Pump is dispensing product, but meter is not registering anything.

Solution:Stop fueling and contact us with details as soon as possible.

Problem:Fuelling is complete, pump is turned off, but you cannot get a receipt.

Solution:Press clear on the receipt printer pad. Insert your card into the card reader. If there is no record of your transaction, try another receipt printer, if available on site. If you do not get a receipt, contact us.



Safe Fueling Tips

  • ALWAYS turn off vehicle when refuelling and turn off any pilot lights or open flames.
  • STAY near vehicle fueling port to avoid hazardous spills. DO NOT LEAVE NOZZLE UNATTENDED at any time during the refueling.
  • NEVER smoke, light matches, or use lighters while refuelling or within 7.5 m of the refueling area.
  • Ensure other sources of ignition, such as other running vehicles, are not within 7.5 m of the cardlock dispensing pump.
  • NEVER prop open the refuelling latch with other items — use only the hold-open latch equipped on the nozzle.
  • DO NOT get back into your vehicle when refueling.
  • DO NOT top off your tank.
  • If a flash fire occurs, back away, and most importantly: LEAVE NOZZLE IN VEHICLE.
  • Always be mentally and physically equipped to perform the refueling task.
  • Do not allow children to refuel.
  • Do not boost your vehicle within 7.5 m of a cardlock pump.
  • Avoid the use of cellular phones or other electronic devices as they may cause electrical sparks.
  • Report any spills by <a href=””>contacting us</a> with details as soon as possible.
  • Locate nearest “Emergency Shut-Off” switch and be familiar with its function.

Static Electricity Safety

Static charges are caused by an imbalance of electrons on the surface of material and can develop by contact and separation of materials, as well as through the transfer of fluids through hoses or pipes. The equalization of the charges can result in a release of a static discharge spark

  • Refuelling fires can occur when:
    • Static charge is picked up when re-entering the vehicle
    • Touching the nozzle without discharging static electricity
    • A static transfer between the fuel nozzle and container
    • A spark ignites fumes
  • Discharge your static electricity before fuelling by touching a metal surface away from the fuel nozzle area.
  • Do NOT re-enter your vehicle while gasoline is pumping.
  • If a fire starts, DO NOT remove nozzle — back away immediately.
  • Do NOT allow children under licensed age to use the pump.

Filling Portable Containers

  • Use only CSA approved containers. Barrels, slip tanks, glass jars and other non-approved containers MUST NOT be filled. Where applicable, grounding cables must be used.
  • Set gasoline containers on the ground, Do NOT leave in the vehicle.
  • Keep the nozzle in contact with the container to prevent the development of static charges.
  • Fill the container slowly to decrease the chance of static electricity build-up and to minimize spilling or spattering.

In Case of Emergency

Fuel Spill Contingency Plan

In the event of an incident immediately notify Emergency personnel

  • Fire Department
  • Police
  • Spill Control

All sites that have petroleum products will display the Co-op Oil Spill Contingency Plan. The plan will include the relevant emergency numbers for that location. Make sure that you know where this contingency plan is and that all the numbers are clearly visible.

The following outlines the Oil Spill Contingency Plan information posted at the Sites:

Oil Spill Contingency Plan

This is the first line of defence in the event of a spill or a leak. All necessary information is on the plan, and is an excellent guideline when reacting to an incident.

Action plan

The action plan is a guideline and not all the steps will be implemented in every spill incident. The action plan portion of this section is composed of 3 steps:

  • Stop the flow of product. If the flow of product can be stopped by shutting off a valve or turning off a pump, then do so immediately.
  • Evaluate fire and safety hazard. If gasoline is spilled then there is a high risk of fire and explosion. The Flash Point of gasoline is approximately 40°C. Diesel fuel can have a flash point of as low as -40°C.
  • Tend to the injured. If there are injured, tend to them. If there are serious injuries, CALL 911 AND GET MEDICAL ASSISTANCE IMMEDIATELY.
  • Shut off sources of ignition — lights, motors, furnaces, open flames. Ensure that ALL ignition sources are eliminated; all power supplies, any electrical devices are potential ignition sources.
  • Warn people of danger — evacuate the area if necessary. Do not panic. If you must evacuate the facility, do it in a calm and orderly manner.
  • Call the fire department, police, medical aid as well as the posted Emergency Site Contact. Each situation will require a different amount of assistance. Use your best judgement to determine the authorities that are required.
Mitigate Risk
  • Contain the spill — begin immediately. After the situation has been assessed, and immediate action has been performed, the product should be contained.
  • Block off drains, culverts, dykes, ditches. Ensure that the product does not spread into waterways or sewers.
  • Surround the spill using booms — straw bales, peat moss, absorbent materials, sand, gravel, earth. All equipment and materials might not be available in every situation.
Report & Clean-up

To be guided by the Emergency Site Contact

  • Report the spill.
    • Notify the General Manager, Graham Getz at ####
    • Source of the spill
    • Approximate amount
    • Location and movement of the spill
    • Action taken
  • Clean-up — begin immediately
    • Commence recovery, clean-up, restoration.
    • Follow up with Spill Mix Report.

The last area on the action plan does not necessarily mean the steps cannot be done earlier. All incidences regardless of the size MUST, at a minimum, be reported to the Site Emergency Contact.


IMPORTANT! — For Retail Cardholders: The operation and safeguards outlined on this webpage are provided for the user’s safety. They should have been both verbally explained and visually reviewed with you by a representative from the retail petroleum department.

When you are satisfied that these steps have been adequately provided, then the operating agreement between yourself and the Co-op must be signed. In the event a Cardlock user is observed operating equipment in an unsafe manner by a fire inspector, the Cardlock card MUST be surrendered to the fire inspector upon request.

No substitute card can or will be issued to a user who has been prohibited from using an unattended self-serve site due to unsafe operation. The fire inspector shall report any conviction for safety violations to the Fire Commissioner. The Fire Commissioner’s office will compile and provide a list of offenders to retail managers of unattended self-serve locations.
