OPERATING INSTRUCTIONS – PLEASE READ PRIOR TO OPERATING
NOTE:
CHECK RECEIVER HITCH HEIGHT 12” – 16” FROM THE GROUND. THIS HEIGHT IS A 10°
INCLINE ON THE PAN FOR EASY UNLOADING OF THE NOSE WHEEL.
General Towing of Aircraft
NLG
1. Drive the “FTD” up to the nose wheel - centering the wheel.
A) Remove the rear safety stop. Then rotate the front stop AFT for tire size 5.00 x 5
(14” dia.) and smaller or forward for larger tires or remove for very large tires (24”
dia. or greater).
B) Place the winch nose strut strap around the nose (use either long or short strap
to give clearance). Then winch the aircraft into the pan and against front wheel
stop.
C) Now place the tie-down straps over the top of the wheel, front and rear of the
nose gear. Pull tight on the straps. This keeps the nose wheel from moving up
and down in the pan. See picture below.
D) Replace rear wheel stop in the closest slot behind tire.
E) Now ready for towing - SLOW
Reverse procedures to unmount from pan.

TOWBAR AND FLAT WHEEL DOLLY
MODEL TY-TB-FTD
Flat Nose NLG Wheel Towing
1. Same procedure as General Towing NLG.
A) Attach to tug.
Main Gear Towing (Max WT. on pan 6,000 lbs)
2. Drive the tow pan close to the flat tire.
A) Remove Towbar from tug and roll up to flat tire.
B) Remove the rear safety stop and front stop before winching into pan.
C) Place the longer strut strap around the gear missing fragile fittings and gear
doors.
D) While winching into pan, a second person will need to hold the Towbar straight.
As the load increases, the Towbar will want to swing left or right. Just try to hold
it straight forward, parallel with the nose of the aircraft. Stop winching 2-3”
forward of the dolly wheels. The further forward in the pan more weight will be
on the Towbar ring hitch.
E) Now place the front and rear tie-down straps over the main gear tire. Also place
rear stop in closest slots behind wheel.
F) Attach tug to nose wheel, tow and move very slowly. Another person needs to
walk and guide the flat tire dolly with steering handle (4) to your destination.
REMEMBER GO SLOW, MAX 2 MPH. PLAN AHEAD. DO NOT OVER TURN.
KEEP A FIRM GRIP ON WINCH HANDLE WHEN LETTING OFF PAN.
DO NOT LET IT FREE WHEEL.

Tire/Wheel Inspection:
•Any tire, no matter how well constructed, may fail as a result of punctures, impact damage, improper
inflation, overloading, or other conditions resulting from use or misuse. Tire failure may create a risk of
property damage and serious personal injury. To reduce risk of tire failure, we strongly recommend you read
and follow all safety information.
•Inspect wheels and tires for wear, cracks, cuts, or damage. Bumps or bulges may indicate separation within
the tire body. A damaged tire can suddenly fail causing damage to property or serious personal injury.
•Inspect tire for adequate tread depth 3/32
nd
inch (2.4 millimeters).
Tire Inflation:
•Always keep tire inflated to the manufactures recommended pressure. Tire sidewall stamping information
will tell you the recommended cold air pressure. Check tire inflation before moving aircraft.
◦Air Hawk 15 X 6.00 6 ply 68 psi
◦Air Hawk 18 X 5.50 8 ply 105 psi
◦Carlisle 5.30/4.50-6 6 ply 95 psi
◦Kenda 4.10/3.50-4 6 ply 75 psi
◦Kenda 4.10/3.50-6 6 ply 80 psi
STA 14 X 5.00-5 14 ply 130 psi
◦Air Hawk 5:00 – 5 10 ply 90 psi
•Use valve caps to keep valve cores clean, clear of debris and to help guard against air leakage.
•Under-inflated tires will cause damage leading to failure that could result in damage to property or serious
personal injury.
•Over-inflated tires are more likely to become punctured, cut, or broken by sudden impact leading to failure
that could result in damage to property or serious personal injury.

CASTER, WHEEL, AND BEARINGS
PREVENTATIVE MAINTENANCE
Simple preventative maintenance for your casters will greatly extend caster and wheel life. The following steps will
help assure that your casters live up to your expectations and application requirements.
COMMON CAUSES FOR POOR PERFORMANCE OR QUICK WEAR DOWN
In many cases, caster and wheel products wear quickly by subjection to abusive or unreasonable demands. The most
important factor in making your caster and wheel products last is choosing the correct caster for your needs.
PERIODICALLY EXAMINE EQUIPMENT
xFrame and Fasteners
xTighten loose bolts and nuts and look for broken welds or deck boards.
xLook for frame distortion due to overloads or impact loads. A distorted frame can cause premature
wheel failure because of abnormal loads on one or two casters.
xLubrication
xAll caster bearings need to be lubricated with a high-quality multi-purpose grease that has good
extreme pressure and anti-wear characteristics, as well as withstands temperature range that fits the
application requirements. Wheel and swivel bearings last longer if lubricated regularly.
xNormal conditions may warrant lubrication every six months, but once a month may be necessary in
extreme applications, such as corrosive or exceptionally dirty environments
xWheels
xCheck for visible points of tread wear. Flat spots may indicate foreign material, such as string, thread,
metal, etc., causing wheels to bind. Thread guards will delay build-up of such materials.
xLoose casters or frozen wheels may also produce flat spotting.
xReplace wheel and/or caster to avoid erratic rolling. After inspecting and making corrections, be sure
axle nut is properly tightened.
xProper Equipment Usage
xOverloading or dropping loads (shock loading) on carts, trucks, or bins may cause sudden wheel or
equipment failure.
xHigh speeds on rough floors can quickly create severe damage to tread and wheels.

ROBERT’S RULES FOR TOWING
1. INSPECTION
Prior to hooking up the Towbar to the tug, make a quick visual inspection of the Towbar.
Check for a bent or damaged frame and for worn or missing parts. Check tire pressure. Check
that you have the proper head installed. DO NOT attempt to tow any aircraft with a damaged or
improper Towbar.
2. RESPONSIBILITY
Operator of the tug must understand that it is his/her responsibility to move the aircraft safely
from “Point A” to “Point B”. NO HOT RODDERS.
3. HOOK UP
When hooking the Towbar to the tug, three things are necessary:
1. The proper tug and Towbar for the size aircraft being moved.
2. The Towbar must be approximately level between the aircraft and the tug.
3. The hitch on the Towbar must move freely on the hitch mounted on the tug.
BASIC TOWING RULES
1. Prior to moving, make sure that full swivel release pins are released (if applicable). Also,
double check that all the tie downs and chocks are removed, and aircraft brakes are released.
2. TOW SLOW, max speed, a brisk walk.
3. NOSE WHEEL TOWING LIMITS: Do not exceed towing limits. If not marked or not known,
do not exceed 30° from center. Be extra cautious on snow and ice.
4. To prevent hangar rash when squeezing the birds together an extra set of eyes helps.
5. Push at a creep to minimize chance of jack-knife” Think Safety” and use common sense.
NOTE:Thousand of dollars in damage can occur in a few seconds while towing. It is estimated that
90% of towing damage is due to operator negligence. We all know when it’s raining or -10°
below zero and you’re on an open tug it’s tough to go at a walking speed.
Thanks for reading the rules.
