Skill: Service a Swing Gate (Full Procedure)
Skill level: 4
Gate Mechanics
Learning Objective
Conduct a thorough, professional service on swing gates — including mechanical checks, hinge inspection, gate alignment, safety device testing, motor function, and customer communication. This helps ensure safe, smooth operation and maximises equipment lifespan.
1. Overview
Regular servicing of swing gates is critical for:
Preventing mechanical wear, damage, and costly breakdowns
Validating a warranty on a new install
Ensuring compliance with EN12453 safety standards
Maintaining correct alignment, limit settings, and safe motor operation
Identifying early signs of any issues, customers prefer proactive maintenance
Building customer confidence and encouraging preventative maintenance contracts
Ensuring customers are aware of their responsibilities, duties and options.
2. Tools & Materials Required
Lithium grease or spray grease
Something to kneel on
Aqua vac for groundboxes
WD40 or similar
Hydraulic oil
Grease gun
Rags, brushes, small broom
Spanners/screwdrivers (hinge and motor adjustments)
Allen keys (motor covers, manual release)
Multimeter (for safety edge / beam testing)
Insulation tester
Silicon sealant
Spare batteries (CR123, AA, coin cell types)
PPE (gloves, glasses, boots)
Phone/tablet (Appsheet + Clik access)
3. Before You Start
Similar to call-out procedure, see separate lesson, call in adavnce with ETA
On arrival
Introduce yourself, state your business
Confirm what you are servicing, sometime there's agate out back you may miss.
Ask customer: “Any issues recently?” — note noise, sticking, slow operation, safety triggers, or faults.
Check customer has manual release keys present and knows how to use them.
Request a remote control, ask for all remotes that need their batteries changing, ask if they want to buy more remotes.
Request keypad codes for testing, ask if they need changing, note them down.
Request enclosure keys if applicable.
Confirm the site is safe for testing (keep people/vehicles/pets away) and that nobody needs urgent access, egress.
Run the gates
Visually do a once over for safety issues. Comunicate with customer on safety regs. The earlier we do this the better to avoid "well the engineer never mentioned this when they were here!"
Visually inspect the system hinges, posts, piers, and gate structure for obvious sagging, cracking, rot or rust. Communicate any issues to the customer as soon as possible.
Check what currently works and what doesn't so we dont get accused of breaking things that were already broken. Confirm with customer before going any further if something, eg the intercom, does not fully work.
Prepare Appsheet and Clik reports ready for documentation, ask customer for wifi access if you need it.
4. Procedure (Main Process)
In all cases when we service you should check, adjust and repair as appropriate. Many items on the list are repairable on a service visit and this is what customers are paying for. This includes adjusting gates, adjusting limit switches, replacing corroded terminals with Wagos or jelly crimps, sealing components etc... Only works that would obviously take you over the allocated time, eg replacing a rusty control box, replacing a worn motor, creating new drainage, should be quoted for separately for completeion at a later date. Note, photograph and quote!
As long as the gates are operational when we arrive, we can carry out a full service. It’s similar to an MOT — you pay for the inspection whether the car passes or not. Even if we notice a significant issue, we still complete the service because the customer has asked for a full assessment of their system, not just the obvious problems like a rotten gate post. For example, if we were to postpone the service due to a rotten post and later discover both motors had failed and the safety systems were down, the customer would have wasted money repairing the post unnecessarily. In that case, they might have been better off replacing the whole system — but by then it would be too late.
Every service includes a safety check in Appsheet. This is the time to do a thoruough check including making notes and photos of all makes and model numbers for main components, eg motors, intercoms, keypads. Even if a safety check has been done in the past, do another one to ensure any price increases are applied.
We allow 90 minutes for a service. This averages out over time. Some take 45 minutes, some take 2 hours.
A. Mechanical Checks
Inspect and grease hinges or pivot points, motor linkages, front and rear motor connection points.
Check for sag, bounce, or excessive play/wear in hinges.
Tighten fixings and look for water ingress or corrosion to underground motors.
Adjust hinges if necessary to restore alignment.
Confirm the gates close onto centre stop with the correct clearance.
Inspect the gate structure for splits in timber, rust, rot or stress around hinge plates.
Check gates physical integrity.
Touch up the paint if appropriate, eg on motor brackets.
B. Motor and Limit Settings
Test manual release (location and availability of keys, confirm customer knows how to use them)
Grease manual releases, BFT ELI can have a grease nipple fitted.
Check and adjust opening/closing limits — leave 1–2 mm before contact with stops.
Run several open/close cycles to confirm smooth and controlled movement.
Physically, carefully, try to hold the gate back to check how hard it pushes. It should be hard enough for reliable functioning, soft enough not to damage people or property. You should be able to stop the gate by hand.
Inspect motor brackets and geometry — no over-travel or awkward angles. Check brackets are tight.
Clean the bulk of dirt from groundboxes, unblock drainage holes.
Check drainage around underground motors, use a bucket of water to confirm. It should drain out in under 30 seconds.
Check play in any underground motors with splined collars, note in cm the amount of play at the end of the gate.
Check/top-up oil on hydraulic systems and check for leaks.
Check mechanical and electrical limit stops and switches, ensure positions are good and lock nuts are tight or apply locktite. Don't let gates open onto objects like kerbs, wall, dense bushes.
Wipe over motor covers.
C. Safety Devices
Photobeams: clean, align, test, seal, replace batteries if wireless. Seal cable entry points with silicon.
Safety edges: test activation, replace batteries, inspect sealing and fixings. Check drain holes are correct, cables are dry.
Check compliance with EN12453 — all entrapment zones covered, no gaps. Something may have changed since the last time we checked, take nothing for granted. See separate lesson on using the Appsheet app "Crush Zone" for this.
D. Electrical
Check enclosures are watertight to approriate IP rating
Check motor windings, L1-N + L2-N = L1-L2. Note abnormal reading.
Check loops <2 MOhms insulation and <5 Ohms > 0.2 Ohms end to end.
Check control box is up to standards, no exposed 230v, no rust holes, no leaks, no structural damage.
Check isolator works and is present. Gates should have a means of isolation withing 3m.
Check connection boxes are watertight, motor connections, all Wiska boxes.
Apply warning stickers.
D. Final Testing
Before you leave cycle the gates open/closed multiple times.
Listen for abnormal sounds or excessive motor strain.
Test force/torque shutoff if safe.
Check for drift on hydraulic operators when powered off.
E. Customer Follow-up
Demonstrate manual release.
Explain safety findings and any compliance gaps.
Recommend upgrades or maintenance where useful eg:
Replacement transmitters
Drainage improvements for underground motors
Updated control panels/intercom
Extra safety devices
App-based access optionsAnything else you would like to see improved. Remember most customers like to prevent issues in advance!
F. Documentation
Complete Appsheet: Select “Service and safety”, log notes, photos, safety checks, and signature. This includes a safety check, this is important.
Complete Clik: Record all tasks, photos, time spent, parts replaced, further actions, and safety compliance. Note who you spoke to and summary of discussions.
Add fresh photos to both apps, things may have changed since the last visit.
5. Best Practices
Call before you arrive, if no answer leave a message.
Wipe over very dirty rams, it looks nice.
Record all info concisely, even the positives. eg "all checked and working well, just the front brackets needed tightening"
Check and demonstrate manual release at every service. The single most important thing on a service.
Take photos of an overview, the hinge areas, motors, intercoms, control board and safety devices for the records.
Check gates and all accessories operate correctly before leaving site. You may have nudged a wire or forgot to plug something back in.
Assume customers want their gates in A1 condition and aim to give them that.
6. Common Mistakes to Avoid
🚫 Missing info needed to quote, eg exact parts or labour
🚫 Not checking or fixing or demonstrating manual releases
🚫 Missing subtle signs of pier/post movement
🚫 Skipping safety edge or beam cleaning/sealing
🚫 Walking off with customers keys/remotes
🚫 Not checking for specific issue with customer
🚫 Failing to communicate with customers
7. Safety Information
Wear gloves and glasses when greasing or handling gates.
Keep body clear of moving gates during cycles.
Isolate power before mechanical adjustments.
Treat underground motor chambers as confined spaces — avoid standing water or poor drainage.
